filechooser: When stopping/clearing BROWSE model, really ensure that we end up in LOAD_EMPTY state

Browse Source 
Previously we could end up in a situation where browse_list_model==NULL, and yet load_state==LOAD_FINISHED.
This is not a valid state.  So, when we get rid of the list model, really ensure that we end up
in LOAD_EMPTY so nothing assumes that there is a valid list model around.
