Travis CI test for PRs fails by default.

In a [PR](https://github.com/Cloud-CV/Fabrik/pull/519), I made no change in the repo except adding a new line in README.md
[Travis check](https://travis-ci.org/Cloud-CV/Fabrik/builds/607585105?utm_source=github_status&utm_medium=notification) fails by default.

## Troubleshooting:

The problem seems to be in `tests/unit/caffe_app/test_views.py` according to Travis logs.

AssertionError: u"Invalid Prototxt\n1:1 : '{': Expected identifier or number, got {." != 'Invalid Prototxt\n1:1 : Expected identifier or number, got {.'

Changes need to be made in caffe_app/views. The syntax does not consider the " '{': " (returned as part of the exception statement).
