This reverts commit e372f3ce6f.
The previous attempt was broken because
EchoTargetPageMapper::fetchByUserPageId() returns a list of
EchoTargetPage objects, not a single one.

Title::newFromId() can return null, and if this were the case the
instance caching would never work, so it would continually make useless
database queries.
Initialize the $title member variable as false to begin with, and use
that to check whether we've already checked Title::newFromId().

We calculate how many messages and alerts are being marked as read, and
subtract them from the count since the database and caches won't be
updated until the end of the request.
For performance, we also get the event_type while doing the
EchoTargetPage lookup query to avoid having to query it individually
later on.
