Merge branch 'gitlab-ee-d39de0ea-backport' into 'master'

Port GitLab EE ProjectsFinder changes

These changes were added in GitLab EE commit
d39de0ea91b26b8840195e5674b92c353cc16661. The tests were a bit bugged
(they used a non existing group, thus not testing a crucial part) which
I only noticed when porting CE changes to EE.
