Describe the bug
Several messages are printed during tns run <platform> and tns run <platform> --bundle which do not give any useful information to the users. Such messages are:
Hook skipped because bundling is in progress. when running tns run <platform>
Stopping tsc watch when calling tns run <platform> and pressing Ctrl + C.

To Reproduce

2. cd myApp

3. tns run <platform> --bundle
   You'll see Hook skipped because bundling is in progress.

4. tns create myApp --ts

5. cd myApp

6. tns run <platform
   You'll see Stopping tsc watch

Expected behavior
Output should contain only relevant messages. The specified messages should be visible only when --log trace is passed to CLI commands.
