Alan Guo Xiang Tan 4b3f65bb26 FIX: Select earliest post when aggregating posts in a topic for search.
This is a revert of
d8c796bc44
and
5bf0a0893b.

Linking to the post within a topic that has the highest rank was
confusing users and hard to explain because ranking is determined via
the PG ranking function. See the following meta topics for the
complaints after we switch to the new ordering:

2. https://meta.discourse.org/t/search-results-should-prioritize-first-post-in-topic-when-title-matches-search-term/175154
