    Revamp trending projects query · b7abba0c
    Yorick Peterse authored
    This changes the query to use a COUNT nested in an INNER JOIN, instead
    of a COUNT plus a GROUP BY. There are two reasons for this:
    
    1. Using a COUNT in an INNER JOIN can be quite a bit faster.
    2. The use of a GROUP BY means that method calls such as "any?"
       (and everything else that calls "count") operate on a Hash that
       counts the amount of notes on a per project basis, instead of just
       counting the total amount of projects.
    
    The query has been moved into Project.trending as its logic is simple
    enough. As a result of this testing the TrendingProjectsFinder class
    simply involves testing if the right methods are called, removing the
    need for setting up database records.
