quiet spec "does not exist" and "already exists" messages

The development and test db names were the same, and rake tries to
create both by default if they're local, so the first try would
succeed and the second would fail.  Didn't seem to break the tests but
output lots of messages if logging is enabled.

Changed the development and test db names so they're different.  Now
both can be created and dropped so rake is quiet.
upgrade Rails test version to 3.2.14

3.2.14 is the latest and greatest.  As a side benefit, this quiets the
"SECURITY WARNING: No secret option provided to Rack::Session::Cookie"
messages that you get if you enable logging.
