[PATCH] python: Fix database.add_message

[Dylan Baker]

b10ce6bc23002d48916b1b2f375480e7540e3164 introduced a new index_file
method as a replacement for add_message. It helpfully made add_message
an alias for index_file, unfortunately it got the signature wrong by
explicitly passing self as an argument.
