picom-trans: fixes when setting transparency with window id

Browse source 
Two problems:

1) the regex used to match the wid in the window tree can match the wid
   appearing in window titles as well.
2) instead of picking the parent window of the target window to set
   transparency, a random window which is listed just below the target
   window will be chosen. not sure why was there a + 1.
