ngIf broken on 1.2.0 release

[matthughes]

Elements with ngIf attribute will repeat the contents as the condition changes. My guess is the bug is it always does an append when going from true -> true. Only removes the children when value goes from true -> false. Here is a very simple example that shows the problem.

This did work as expected as of 1.2.0.rc3.
