Travis badge reports failures on non-master branch

[kulinacs]

Currently, a failed build on Travis marks the TravisCI badge as failing, whether it is on master or not.

It seems the bug may lie in:
https://github.com/ansible/galaxy/blob/master/galaxy/api/views.py#L873

TravisCI does not currently allow reporting on specific branches, but includes the built branch in the notification. Instead of setting the branch solely based on the notification received, there should likely be a comparison with the branch specified by the role (or the default used in import) to check if the status should be changed (and which status badge should be used)
