Update the test suite.

- monkey-patch our own monkey-patched idle_call to run events immediatly
  rather than adding them to the event queue, and add a fake transport
  with a fake socket.
- remove the test file related to xep_0059 as it relies on blocking
  behavior, and comment out one xep_0030 test uses xep_0059
- remove many instances of threading and sleep()s because they do
  nothing except waste time and introduce race conditions.
- keep exactly two sleep() in IoT xeps because they rely on timeouts
