Moving items from a container using AIM seems to be broken

[x-qq]

Describe the bug

Advanced Inventory Manager system does not seem to allow manipulating items inside a container.

Steps to reproduce

1. Spawn a new character.
2. Spawn "messenger bag", "pair of combat boots", "pair of sneakers".
3. Insert boots and sneakers into the messenger bag.
4. Drop messenger bag to the adjacent tile.
5. Now attempt to move both items from inside the messenger bag to some other AIM location like your inventory or another tile by selecting the messenger bag and using the C key.
6. Notice that AIM is not showing all of the bag contents.

Expected behavior

Selecting a container (possibly a nested container) in AIM and pressing C should display all contents of this container.

Screenshots

I've been experiencing this in builds since at least may -- I guess it's been that way ever since nested containers were introduced?

I believe the culprit is in advanced_inv_pane, where this advanced_inv_listitem constructor is only being fed a single item_location, rather than a list of them. I'm unsure how to fix this myself, however. https://github.com/CleverRaven/Cataclysm-DDA/blob/51f9ad845ff6d0d446aa7d721d0f3e9406b81885/src/advanced_inv_pane.cpp#L227
