When a connection is dropped but broken, we notify all waiting get requests that they should try again. This is done in order to ensure we have enough pending connections to serve all in- flight gets. Because only a single connection dropped however, we only need to notify one waiter to refresh, not all of them.

I'm moving this from #223 just to prove it doesn't break any tests.

To get djc/bb8#186 and djc/bb8#189
which fix potential deadlocks (djc/bb8#154).

Also, this (djc/bb8#225) was needed to prevent a connection
leak which was conveniently spotted in our integration tests.
