deleting test_add_profile_ok after executing test body

[sturmianseq]

This PR aims to improve test reliability of test test_add_profile_no_param by deleting test_add_profile_ok after executing test body by calling method executor.execute_command with corresponding arguments.

The test can fail in this way if test_add_profile_ok is not deleted:

        out, err = capsys.readouterr()
>       assert msg.BUILD_REQUIRED in out
E       AssertionError: assert 'This parameter is required!' in '[ERROR] The profile test_add_profile_ok exists. Did you mean -u/--update?\n'
E        +  where 'This parameter is required!' = msg.BUILD_REQUIRED
