Fixes bug #13477 AGS: Heroine's Quest intro shows portrait bug
This old commit was trying to fix a problem in old game(s), when
character was set to a loop with no frames. In such case the old
engine would seek for the first loop with frames, starting with 0.
The condition for doing so was made incorrect though: instead of
testing simply for a empty loop, it tested for frame number being
outside of the current loop's frame range.
This broke games where e.g. some walking view's loops were shorter
than the others.
A replacement is a condition that tests exactly for an empty loop
instead. The frame exceeding a loop's frame count is fixed later
along the way, so it's not a problem here.
