server: reverse: fix function argument order

This patch fixes the following bugbear issue:

    lona/server.py:996:17: B026 Star-arg unpacking after a keyword argument is strongly discouraged, because it only works when the keyword parameter is declared after all parameters supplied by the unpacked sequence, and this change of ordering can surprise and mislead readers.
        *args,
        ^
