The more I've thought about the underlying issues involved in #7956, the more I believe the time has come for Meteor to stop providing custom implementations of babel-runtime/helpers/* and instead simply rely on the npm babel-runtime package.

This pull request adds babel-runtime to the default package.json file for new apps (a la meteor-node-stubs), installs those basic packages when running meteor test-packages (which is something we should have been doing all along), simplifies the Meteor babel-runtime package (it now throws an error if babel-runtime has not been installed), and cleans up some other logic that no longer matters.

I'm torn about whether to include this in 1.4.2.1 or wait for 1.4.3, though I believe it is the most reliable fix for #7956, which is (rightfully) in the 1.4.2.1 milestone.

Many tests were broken by the initial version of this pull request, since we weren't installing babel-runtime in the various test apps used by meteor self-test ..., but that should be fixable.

Add babel-runtime to the default new-app package.json file.
In light of issues like #7956, I would very much like for app developers
to be responsible for providing node_modules/babel-runtime, and for the
Meteor babel-runtime package to stop attempting to implement a subset of
the helpers.
Install basic npm dependencies when running test-packages.
At this point, the only dependencies installed in this way are
babel-runtime and meteor-node-stubs, but that set of packages will
expand in the future as we move more dependencies to npm.
Simplify Meteor babel-runtime package by relying on npm version.
Though this may seem like a significant change, this package will still
work for older apps as long as the developer follows the instructions
about installing the babel-runtime npm package.

Helps with #7956.
Make --prepare-app install default npm deps to fix self-tests.
Tests were broken by the new dependency on the babel-runtime npm
package, but fortunately all those tests run `meteor --prepare-app`
whenever an app is created by a self-test, so this change should fix
most of the breakages.
Run installDefaultNpmDeps whenever creating self-test apps.
Some tests disable the --prepare-app step, but still need babel-runtime
to be installed.

Cache .meteor-portable values temporarily in memory.
This is another way to fix the bug I previously fixed by passing
options.allowSyntaxError to optimisticReadJsonOrNull.

To reproduce the bug (and/or verify that it is fixed), run the following
commands in a terminal:

  rm -rf meteor/packages/npm-mongo/.npm
  meteor/meteor --get-ready

Before these two commits, optimisticReadJsonOrNull would throw a
SyntaxError when reading one of the .meteor-portable files because an
asynchronous write to the same file had not yet finished.
Move default npm deps install function into own module.
This extraction was necessary because importing tools/cli/commands.js is
not entirely side-effect-free, and was interfering with older tests.
Attempt to fix "run --once" test by giving Mongo a chance to exit.
This test has been failing intermittently on Circle CI.
