screen-cast/virtual-src: Don't recreate the virtual monitor on resizes

Browse Source 
Keep the virtual monitor around if it's being resized. This reduces the
number of unnecessary object rebuilding that happen during monitor
rebuilding.

This changes finalize() vfunc into a dispose() vfunc in the abstract
stream source object implementation, as it needs the abstract stream
source object to close the stream early, so that various signal
listeners get disconnected early.
