At first this appeared to be a multi-db bug but after some invesitgation it was clear that this can occur just by calling `establish_connection` from ApplicationRecord. After some investigation we found that this only occurred when using fixtures. The console boots fine, the server runs fine, and the tests even run fine if we used paralellization or eager loading in the tests. I tracked the issue down to the line that calls `self.connection_specification_name = name` in the SchemaMigration changes for Rails 6.0. But how can this be? That is not that major of a change? How could `connection_specification_name` be a problem? First `connection_specification_name` caches the name of the connection specificatio. Second, fixtures were incorrectly holding onto a reference to that connection. So when you went to run the tests the models wouldn't be connected and when the fixtures tried to load the data it would choke on that unconnected database. The changes here move the connection into a lambda so we can call it when we need it rather than blowing up before the model is connected.
