travis: enable test-cases check of ciao-storage
travis: enable test-cases check of ciao-storage

The ciao-storage component does have some ceph test coverag in BAT, but
it does not have much in the way of unit tests as is highlighted in
issue #940.  By enabling test, the directory's coverage will start to
show up in coveralls.
