[MCPE-188635] Renamed containers don't stack after placing and breaking

If you rename a container in an anvil, then place and break it, it no longer stacks with other similarly named containers.

1. Get a stack of chests

2. Rename all of them in an anvil
3. Place one
4. Break it

Expected behavior
It keeps its name, so it should stack with the other ones

Observed behavior
The name is kept, but it still won't stack

Confirmed in Android

This bug happens because the RepairCost tag is removed from the container after placing the container and breaking it.
