Fix Error 500 when searching Wiki pages
If a Wiki page turns up a hit in the search results, an error will occur:
```
Completed 500 Internal Server Error in 836ms

An unhandled String containing the name of the Wiki page would be provided to the URL path generator. This MR handles that case.

Unescape branch names in compare commit
The upgrade in GitLab v7.9 to Rails v4.1.9 caused all branch names in the compare commit mode to be escaped (e.g. `/` to `%2F`). The compare mode would not always work when comparing against branch names with a forward slash.
Opted to unescape the branch name rather than use a wildcard segment to prevent escaping slashes because it seems like a more sensible URL. The slashes in this case aren't really represented by a tree structure (e.g. /compare/one/two/branch..another/branch/here).

Allow primary email to be set to an email that you've already added.
Fixes gitlab-com/support-forum#106.
When the user sets their primary email to an email that they've already added to their account, this patch makes sure that secondary email record is destroyed, and a new email record is created for the old primary email. This is based on the assumption that in this case no email was meant to be deleted, but the user simply wanted to change which of their emails is primary.
