The "q" key was removed while addressing ticket #36411. Despite
`MediaType.params` is undocumented and considered internal, it was used

the `q` key in `params`.
Thanks Anders Kaseorg for the report.

The for_save flag wasn't properly propagated when resolving expressions, which
prevented get_db_prep_save() from being called in some cases. This affected
fields like JSONField where None would be saved as JSON null instead of SQL NULL.
Regression in 00c690efbc0b10f67924687f24a7b30397bf47d9.
Thanks to David Sanders and Simon Charette for reviews.
