urisourcebin: Fix parsebin handling

Browse source 
The goal of !3601 was to make sure we don't end up with non-streams-aware
adaptive demuxers. Since we know that parsebin is streams-aware, just remember
that and handle them that way.

Fixes issues with some scenarios where parsebin might add pads *before* the
collection is posted on the bus
