Subject: Remove global `Dataset_Getter` variable

Since the `__post_init__` method in the 'DatasetType' class checks
whether data is in redis before hitting the database, it does not
matter whether there is a global object of the type, as long as we
make sure to call the object correctly.

This commit makes that happen.
