Missing spec coverage

So there are three files currently not fully covered by specs:
 -- /admin/properties_controller.rb
 -- reservations_controller.rb
 -- users_controller.rb

The admin stuff we haven't done yet, and most of the missing stuff in the users_controller has to do with the user profile, which we also haven't done yet.

The reservations_controller on the other hand has a lot of stuff leftover from before that I *think* we're not using/don't need anymore, but I'd prefer to let somebody else take another look at that before I just throw that stuff out.
