When enabled make sure we load org-roam-protocol

Org roam protocol can be used from outside Emacs and as such, loading it only
after some org-roam buffers are opened defeats the purpose. Without this change
the org-protocol links won't work after emacs restart until at least one
org-roam buffer is loaded.

Fixes #14487
