raw: Fix raw links to branches with a slash in their name

When a branch has a slash in the name, the raw servlet was not able
to find the path under that branch. This is due to the replacement of
the forward slash character for URLs. It was not taken into account
when comparing the branch name later.

This fixes #1290 and its duplicates #1234 and #813.
