conman:  Handle WPACtrl.request errors.

This commit addresses the following problems:

* conman would sometimes call WPACtrl.request when the WPACtrl was not
  attached.
* conman didn't catch the wpactrl.error that wpactrl.request may
  throw.
* The unit tests would not pass if the system didn't have the real
  pywpactrl installed, beacuse the fake wpactrl didn't have the
  necessary fake classes.  I verified this by removing pywpactrl from
  my machine, seeing the tests fail, adding the fake classes, and then
  seeing them pass.
