Fix T54766: "Record With"-NLA "Push Down" discards Blend Mode, Extrapolation, and Influence

Applied similar fix to T54233 to get the "Record with NLA" feature working with
active action blending + influence settings. Extrapolation is explicitly ignored
though, as it shouldn't be used with this feature (i.e. it is already disabled
with the new strips and also on the animdata by default)
