Fixes incorrect handling of prioritized inventories

Prioritized inventories are not longer used twice for storing leftover
items and thus finally reporting twice the amount of storable items when
they are the only possible option to store something.

Also fixes import buses now respecting the amount of storable items inside
the network instead of trying to place the exported items back and failing
on any restricted inventory, potentially voiding the overflow.

Fixes #1892
