Subject: fix(ngRepeat): correctly track elements even when the collection is
 initially undefined

Previously if the collection model was set to undefined on the first digest,
the repeater would get confused and not use the correct tracking function
for associating model with dom elements in the repeater.

Closes #4145
Closes #3964
