Change subject: Disconnect bound reference list events on teardown
......................................................................
Disconnect bound reference list events on teardown
Reference lists would never disconnect, and some transactions would cause them
to be "updated" even though they don't have a document anymore.
A way to test this is to insert an image in a document with some references.
When you click apply, it crashes.
The solution was to make sure we actually disconnect from the internalList and
listNode on teardown.
