Stop passing destructured str to wrap_destructured_import
Stop passing destructured str to wrap_destructured_import

Since we know we are wrapping a destructured import, we can just access
the destructured string via the destructured_string method (which relies
on the destructured_variables accessor on the object). This is another
step toward cleaning up the #to_import_strings method.
