Fix #483 and #481

Exact matching of requested pages

- /page is no longer the same as /a/page
- Deleting /page only deletes /page (before it would delete /a/page instead of /page)
- Edit currently breaks the unit tests if exact matching is enabled
- Fix redirect on create
- Add @giga's checked_dir = '' fix https://github.com/giga/gollum/commit/936958b47324a09c683cb90a2560484b47e09529
- Fix create unit test
