Fixed issue where exporting traits would throw an error if a dataset's

group didn't have an InbredSetCode set in the DB
* wqflask/utility/authentication_tools.py - Changed get_group_code to
return an empty string instead of None if InbredSetCode doesn't exist
for a dataset group
* wqflask/wqflask/views.py - Changed zipped export filename to
"export_(datetime)" instead of "collection_(datetime)" since this export
can occur from both the collection page and the global search page
