Inconsistent prefix handling for redirection

[Xon]

Affected version

2.2.7 Patch 1

In XF\InlineMod\Thread::ApplyPrefix, the code bails if the thread is of type redirection.

You can however edit the thread's prefix (and title!) by hitting the threads/edit route.

However the 'edit' link doesn't show up in the threadlist despite this potentially being useful.

We use (permanent) redirects pretty actively as an alternative to crossposting the same OP in different fora. We can open the update modal for the redirect (ex to change the prefix) via the moderation toolbar -> "Apply prefix...", but when saving the changes it does nothing (closes silently without an error).

Would be great if this works
