Fog::Model#wait_for: eliminate inner retry loop

AWS frequently takes more than 3 seconds for an instance to appear.
Rather than having the overlapping timeouts for reload and
instance_eval, simply make them both occur with the same timeout.

 + Easier to follow flow

Rectify issues with tests and status

* Since the server will remain in ACTIVE state for up to a few minutes, do not
  set the status (to prevent a situation where the state bounces between
  PREP_RESCUE and ACTIVE).
* Add format() test for the call to #rescue
* Remove extraneous sleep from the test against #unrescue
* Remove immediate tests for state.  Rather, depend upon the wait_for function.
