EntryRestController::getEntriesExistsAction: always find by hashed url

Simplify the logic from #3158 by hashing all the urls from the request,
and only doing a search by hash. This allows to get performance benefits
from the new indexed hash column even when using older clients that do
not hash the URL in the request.

Fixes: #3158, #3919
