Fix wrong information used for stamp when "Strip Metadata" is used

Such configuration used to cause quite confusing situation when
stamp will use actual scene's statistics but metadata from strip
will be used for the saved file (basically, causing different
information stamped and saved as metadata).

Don't think it was desired behavior and it's something what
artists here in the studio wants to be fixed.
