[squeak-dev] Bug in #tryInvokeHalo:

Hello all,
To see a bug in the halo targets dispatch mechanism, do the following:
- Open a fresh image, use the alphabetical list from the "new morph..."
item in the World menu to get a SameGame morph.
- Put the SameGame morph above the "Welcome to Squeak" window.
- Blue click three times in a row within the SameGame inner part: this
will give a halo to one of the small square tiles.
- Now blue click on the grey border of the SameGame morph (say, at
left): instead of that morph getting the halo, it will go to the
"Welcome to Squeak" window in the back. That is the bug.
Reverting #tryInvokeHalo: in PasteUpMorph to its previous version fixes
it (the current implementation discards the first morph in the targets
stack, which happens in this case to be the target we do want).
