power_LoadTest: Fix race with closing windows

There's a race in power_LoadTest where the windows are closed for the next loop
from a function scheduled at the end of the previous loop. This just removes
that function since the windows we open during the test will close on their own
and the next loop will close any preexisting windows.

BUG=chromium:424391
TEST=run full power_LoadTest and make sure that:
grep "Didn't get status back from power extension" debug/power_LoadTest.DEBUG
doesn't find anything
