Comment 44 for bug 1202952

Question on the grizzly patch v2 from comment #41 --

in token/backends/, at line 99 do
 token_id = token.unique_id(token_id)
then at line 101
 ptk = self._prefix_token_id(token.unique_id(token_id))

so now token_id has had token.unique_id() applied twice when passed to self._prefix_token_id(). Seems strange would need to double-apply an operation, so wondering if this is intentional.
