Fix 2i tests that were missing the new record.
Fix mapreduce test (bad formatting of term).
Fix bucket properties tests.
Unlink the socket process in the counter test so eunit doesn't exit.
Fix list-keys and list-buckets tests.
Fix identification of the PB listener.

"pb://127.0.0.1:8098" rather than by the module name, so we match on
the module name in the list of modules in the child spec.
