pre_dispatchis a new method on theSignedExtensiontrait from substrate. We don't care about this internal implementation detail on thesubxtside, but we require this trait to be implemented because we are using theSignedPayloadandUncheckedExtrinsictypes fromsp_runtime.The other option is of course to define our own local types and traits to remove this direct coupling, but that need some careful consideration.
In the meantime this makes things compile and continue working against the
substratemaster branch.This also fixes an issue with duplicate substrate dependencies.
