Restrict noneable parameters to be of type Object

This fixes a number of crash bugs, as passing None to these "noneable" parameters had resulted in a crash.
Technically, this change *appears* to change the API. However, as these params were never truly successfully "noneable", this is not an incompatible change.

RELNOTES: None.
