During review of the new setting for controlling interdiff filtering,

some logic was updated that ended up breaking a test introduced in the

change for the new interdiff filtering algorithm.
This change updates the affected tests to pass the state needed to

enable interdiff filtering, and also fixes the call to

filter_interdiff_opcodes() in the opcode generator to pass in

request (which is currently unused, but was noticed after fixing the

test).

Unit tests pass.
