action_sheet test [nfc]: Simplify prepareRawContentResponse… helpers

Their callers always give them the shared store prepared by the
setup helper setupToMessageActionSheet.  Have these helpers just
use that directly.

If in the future we end up having a use case for customizing this
behavior, it'll probably be most convenient to have them accept
a connection instead of a store, anyway.
