Travis: remove status functionality
Travis: remove status functionality

Unfortunately, we need to remove status functionality as it exposes an information
it should rather not. There is no other way we can do it in the pull request coming
from forks (most of our PRs are from forks). It is better if we use pass/failure what
Travis provides. The information are in the logs. It should always print the status info at
the very end. A test should have "echo Failed with a reason...."
