map: update active items cache when removing contents

[andrei8l]

Summary

None

Purpose of change

Removing active items from an otherwise inactive container does not properly update the active item cache because the container's processing speed changes.

Fixes the place_player_can_safely_move_multiple_submaps failure that has been plaguing CI jobs lately, for example:

Describe the solution

Update the active item cache when removing items with item_location::impl::item_in_container::remove_item() (used by shop restock code, for example)
If the container of the item-to-be-removed isn't active (anymore), remove it from all active queues.

Testing

New test unit

Also ran while :; do ../build_lto/cata_test --rng-seed time --min-duration 0.2 --use-colour yes "npc does healing",place_player_can_safely_move_multiple_submaps;ret=$?;if [[ "$ret" != '0' ]];then break;fi;done for a couple of hours with no issues

Additional context

The test unit place_player_can_safely_move_multiple_submaps is really bad because it doesn't set up anything and can only catch issues by happenstance. However, it caught this (almost) completely unrelated issue so I'll leave it alone for now. I've only updated it a little bit so it's a bit more clear what's failing.
