m2m historical records are saved even when SIMPLE_HISTORY_ENABLED = False

[MattFanto]

Describe the bug m2m relationships ignores the SIMPLE_HISTORY_ENABLED = False, even when disabled the library is still saving the historical record. This is causing me some issue when loading Django fixture using loaddata

To Reproduce Steps to reproduce the behavior:

1. set SIMPLE_HISTORY_ENABLED = False
2. save a m2m relationship
3. you will see the record in the historical DB

Expected behavior If SIMPLE_HISTORY_ENABLED = False no historical record should be created for m2m relationship
