Fix bug with gitaly page method
https://gitlab.com/gitlab-org/gitlab-ce/issues/42039
The line where the presence
could be the solution is in wiki_service:55
Basically, the problem is that when we call the page
method in wiki_find_page
we should not convert the dir to nil
if it is empty. Other solution could be to pass the param exact
to the wiki page
method.
