This solves an N+1 query problem where for every project we'd query the
creator separately just to figure out what avatar to display.

The method User#projects_limit_left would run "personal_projects.count"
but such a query is not memoized. As a result multiple calls to
User#projects_limit_left would result in multiple COUNT(*) queries being
executed.

To work around this this commit adds User#personal_projects_count which
simply memoizes the result of the COUNT(*) in an instance variable.

The "events" table has a foreign key on "events.project_id" with a
cascading delete. As such it's impossible for an event to have a
non-existing project ID.

In various places we check if the same relation would return projects.
This is done using "any?" which will run a COUNT query with any
LIMIT/OFFSET values still applied.

To work around all this we introduce 2 helper methods that take care of
doing the right thing. This leads to the produced queries being simpler
and fewer queries being executed.
