We might also want to consider reduce the number of
connections in the tests. However I just tried setting it to 1
and that doesn't seem enough for feature tests.
So that we could make sure migration tests could run even if
geo is not setup in EE.
This is because we have a model like this:
``` ruby
class Geo::BaseRegistry < ActiveRecord::Base
def self.connection
raise 'Geo secondary database is not configured' unless Gitlab::Geo.geo_database_configured?
super
end
end
```
