Add the missing common/helpers.ts to package.json

[ekpyron]

Fixes #622.

I guess this is enough to fix the issue, but maybe better if @cameel and/or @stephensli confirmed.

@cameel this will do it, please just do a npm build-tarball and check the tarball output to see if the content contains everything required. If anything else is missing (hopefully not) include it in this PR @ekpyron

Looks like "common/types.js" should be added too as it is also imported in linker.ts

[ekpyron]

As far as I can see dist/common/types.js (i.e. the js file built from common/types.ts), is empty and not imported by any of the other built js files - probably since it's only relevant for typescript and does not carry over to js...

[nataouze]

Yes you are right, it is not present in the built linker.js file. Thank you

[cameel]

Looks fine to me but not approving yet since I'd like to play with it a bit tomorrow and also investigate why this does not trigger a failure in CI.

[stephen-slm]

@cameel I would not invest much effort as #615 updates the exported files. Which can be seen here

solc-js/package.json

Lines 38 to 44 in 95ca828

	"files": [
	"common/*.d.ts",
	"common/*.js",
	"bindings/*.d.ts",
	"bindings/*.js",
	"*.d.ts",
	"*.js"

[cameel]

Well, we still need to find out why it went through our tests unnoticed. And then, when we fix the tests, we should rebase all these PRs on top of that to make sure the fix still passes them. I hope that the missing entry in package.json is the only problem but we really can't be sure of anything until tests are working properly.

[cameel]

Looks like there were no other issues. Tests with my fix in #625 now detect this problem and they do pass when rebased on top of this PR. See #625 (comment).
