Each of the individual query chunks has their own test, in addition to a
test for the full combination of parameters that could influence a
query.
There is also a bugfix for the tag query in here, since I want, as much
as possible, to have passing tests on every commit.
todos in rest of month means all todos after next week in the current month. The test failed
if the todo was created in next week and that week being the last week in the month. In that
case the todo should not be returned by rest_of_month since it is in rest_of_week
