handle moveFromStorage within the same storage even when storage wrappers are applied to the source storage

the target storage doesn't need additional handling for wrappers as the wrappers implementation of moveFromStorage already deals with that

Any storage based on local storage isn't affected by this as local storage already has it's own way of handling with this
