Avoid primary DB query for non-talk page edits

Browse source 
While investigating primary database queries as part of T370304,
we found that EventDispatcher currently issues a primary DB query
to fetch the previous revision of the newly created revision on
every edit, but discards the result for non-talk pages. So, as an
optimization, have it fetch the previous revision only after the page
has been established to be a talk page.

Bug: T370304
