Missing task entity from rules.files.deriv.preprocessed_data.meg_meg_common

That derivatives rule is getting task required from the raw meg rules https://github.com/bids-standard/bids-specification/blob/master/src/schema/rules/files/raw/meg.yaml

Why is it using derivatives files rules and why isn't it hitting the correct rule for fif extensions.

.fif is a valid mainline _meg extension.
