Relax constraint on Wiki IDs, since subdirectories can contain spaces
It looks like if you have a Wiki page in the following form:
group /
group / text.md
For most Wiki pages, GitLab substitutes a space for -
in the slug. However, when there are subdirectories involved, the space is left untouched. This causes an exception because the id
constraints in the route prevent this from being a valid route.
Removing the constraint fixes the problem.
