Refactor a bunch of the tests - now they only take about 4s instead of two minutes!
No need to create the fixtures really - we aren't doing anything with them.
Ask about loading fixtures (defaults to no).
Only load one user as a fixture. Now that the tests all create their own user, there's
no need for all the extra users.
don't load the fixtures in travis - they aren't needed anymore.
