Boaz Shuster 48a26ba9e4 Add an integration test for bug #31392 regression
This verifies that bug #31392 won't surface again.

To reproduce the bug:
1) docker run -dit --name a0 busybox sh
2) docker run -dit --name b0 --link a0 busybox sh
3) docker rename a0 a1
4) docker run -dit --name a0 busybox sh
5) docker rm -f b0
6) docker run -dit --name b0 --link a0 busybox sh
