gtk: Fix crash on Analyze RTP stream
When updating the RTP streams list, the data associated with the current
selection becomes invalid when the old list is cleared.
gtk_list_store_clear somehow triggers the selection callback which
attempts to access the invalid memory.
Avoid this by disabling selectability while clearing the list.
