Write tests for ReservationsController

[austinczarnecki]

This has its own issue because it's huge and needs to be done before we can start refactoring.

Since this is some of our core functionality, adding this to milestone 3.3.0. (I thought that @ebmaher wrote some of these, but I can't find the branch, so we'll just start anew.)

Plan:

• Write super-basic happy/unhappy path tests (response is success, assigns a variable, renders template v. response is redirect, sets the flash, doesn't render template) for all routes
  • GET index
  • GET show
  • GET new
  • POST create
  • GET edit
  • PUT update
  • DELETE destroy
  • GET manage
  • GET current
  • PUT checkout
  • PUT checkin
  • GET checkout_email
  • GET checkin_email
  • PUT renew
• Write more detailed functionality tests for each route
