commands: refactor commands.py to avoid using no_wait arg.

In the commands.py, the RunHWTestSuite method will call run_suite script twice,
one with create_and_return arg to create a suite job and exit, and the other
call with 'mock_job_id' arg to wait for the suite results. However, when we
specify --no_wait is True, the second call does not wait for results,
thus become unnecessary. So, refactor commands.py to call run_suite
script twice only when we explicitly specify to wait for results, and
omit the --no-wait arg.

BUG=chromium:533621
TEST=unittest and tryjob test with expected results.
