Remove `DumperTest` (#90)
Remove `DumperTest` (#90)

The `DumperTest` class is FUBAR in its design: It mocks the DBAL connection, making assumptions about the order and semantics of the queries the `Dumper` class will issue.

As long as we need to query the database for schema information and/or use the DBAL schema tool that does it, probably the only way to go for code like this is to do real functional/integration tests against a real database.

Since this broken test is getting in our way in #88, let's remove it.
