feat(feedback): rm unused post-process-group flag from test

[aliu39]

No references anywhere else in sentry and getsentry

[aliu39]

Oops, looks like it is! Test passes without this flag though. Doesn't seem like we have post process tests

@JoshFerge ok if I remove this reference? Or was there a reason we need it for this test?
