Bump bb8 from 0.8.1 to 0.8.6 (#709)

* Update bb8 to 0.8.6

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.

* Ignore ./.bundle (created by dev console)
