`tns run android --clean` does not work as described in help

[dtopuzov]

According to CLI command line help:

* --clean - If set, forces rebuilding the native application.

Actual behavior with master branch:
I can't see something different (such as rebuild of the app)

Steps to reproduce:

tns run android (and start make changes on the project)
Ctrl+C
tns run android --clean => No rebuild is performed.

We should take same action to make help and behavior consistent - either fix the command or fix help.

Agreed, I just came here to report this -- I ran into this when I did:

1. tns create project
2. tns run android
3. Make some changes
4. tns run android --clean

I had expected to see --clean do a full reset, but it did the normal live sync.
We really need --clean to do a full rebuild; so that I no longer have to do a:

tns run android
tns build android
tns run android 

To get a "clean" build...
