Settings are stored in the database, and so any changes to the settings
done during the tests are automatically rolled back between one test and
the next one.
There were also a few places where we weren't using an `after` block but
changing the setting at the end of the test.
When editing the map of a proposal or investment(the mappable) the
updated_at attribute of the mappable was not been updated and so the
map still displayed the old location after updating it
