When using gitlab for a branch named bug/travis-branch-name travis clone step fails to clone becuase the branch is reported as travis-branch-name instead, causing the clone step to fail
in other words travis uses:
git clone --branch=travis-branch-name yada yada
instead of
git clone --branch=bug/travis-branch-name yada yada
with gitlab reposotories
