GER: Use Itempool Count for Minimal handling (#4649)

Browse Source 
* uses itempool count vs unfilled location count instead of counting prog_items values which could have custom counters

* move unfilled location check to before can_reach

* add tests for successful minimal GER call with extra collect override prog_items in the pool to regression test issue fixed in this PR
