The "handoff an item immediately after disconnecting" fails on some systems

[stass]

Hi!

I have a linux system where the "handoff an item immediately after disconnecting" test
fails for some reason. I presume, that's because it is a bit slower, as the same test passes on my FreeBSD laptop, or maybe I'm stepping on some concurrency issue.

I used the following change to make the spec retry the test several times. It solves the issue for me.
