avy.el (avy--overlay-at-full): Work-around 20607

Browse Source 
* avy.el (avy--overlay-at-full): There's a problem when there are two
  overlays at the same point in the same buffer, but in different
  windows, *only if* they are of different length. Make them the same
  length to work-around this bug.

See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20607

Fixes #47
