Fixed settings redirect issue and custom head display

Fixed settings redirect issue and custom head display

- Fixed issue where redirect for `/settings` view would not be ran
  through base url generator so would not create a correct path in some
  cases. Now routed through controller with normal redirect.
- Fixed custom head content being active on settings pages due to route
  name changes, for when viewing settings, in last release.

Fixes #3356 and #3355
