The specs for Settings::DeletesController include an example that
sets Settings.open_deletion to false and expects the "if deletion is not
available, redirect to root" logic to run.  However, this spec does not
set up a user, which means that the spec (intentionally or otherwise)
expects this redirection to work with unauthenticated access.

We should preserve that behavior.  To do so, we prepend the deletion
check to the action chain set up by Settings::BaseController, so that
said check occurs before the authenticate_user! check.

i18n: Update Japanese translation

Signed-off-by: Marcin Mikołajczak <me@m4sk.in>

* Break out nested relationship API keys

This closes #5856 by restoring the existing behavior of the `muting`
and `following` keys (returning booleans rather than truthy or false).
It adds `showing_reblogs` and `muting_notifications` keys:

* `showing_reblogs` returns true if:
  1. You've requested to follow the user, with reblogs shown, or
  2. You are following the user, with reblogs shown.
* `muting_notifications` returns true if you have muted the user and
  their notifications as well.

* Rubocop fix

* Fix pulling reblog/mute status from relationships

I could swear this had passed tests before, but apparently not.
Works now.

* More test fixes
