gramps/test/GrampsDb/GrampsDbBase_Test.py
Richard Taylor b2b6cb0ad5 * src/EditPlace.py: changed display_references to use find_backlink_handles
* src/EditRepository.py: modified to use  find_backlink_handles and fixed subtle bug
	* src/RelLib/_Source.py: added reporef_list to referent object lists so that backref
	are put in reference_map
	* test/GrampsDb/GrampsDbBase_Test.py: added unittest for source/reference backlinks
	* test/GrampsDb/GrampsDbTestBase.py: added unittest for source/reference backlinks
