`tns run android --no-watch` does not work as described in help.

[dtopuzov]

According to CLI command line help:

* --no-watch - If set, changes in your code will not be reflected during the execution of this command.

Actual behavior with master branch:
All changes are synced.

Steps to reproduce:
tns run android --emulator --no-watch and start making changes on the project.

Ideas:
--no-watch is almost the same as --justlaunch.
We can remove --no-watch or at least hide it from help.

No, NO please do NOT remove --no-watch.

We need this in some cases:

1. I'm demo'ing (don't want the app reseting under me, when I show/edit code).
2. I'm doing debugging; in some cases when I am stepping through code; I don't actually want my changes to be applied until I'm totally done with the session and restart the debugging.

We won't remove it, we just fixed it to work as it did before.
