update: fix dependency processing

Browse Source 
The previous commit broke the layer order, e.g.:
A -> B -> C -> D

The algorithm is checking the dependencies one by one, and until we find D, add
D to layerquery_sorted, and add it "collections", the one in "collections"
means it's dependencies are OK, then C, B and A will check against collections,
so that update_layer.py will update them one by one. The previous commit added
A/B/C/D to collections directly, so that when check against it, all the
dependencies are met, thus broke the layer sorting, and then there would be
failures if we pass layer A to update_layer.py before B, C and D (suppose they
are newly to database). This commit fix the problem.

BTW., why I use collections to record the one whose dependencies are matched,
but not directly use layerquery_sorted, it is because collections contains both
the ones to be added/updated and the ones in database, but layerquery_sorted
only contains the ones to be updated/added.
