* Tests: add a test that created items and locations exist in the datapackage
* move FF validation to `assert_generate` and remove test exclusion
* test created location addresses are correct
* make the assertion proper and more verbose
* make item count test ~~a bit faster~~ a lot nicer
* 120 blaze it
* name test multiworld setup better and fix another over 120 line in FFR
