python: Fix Idl.run change_seqno update.

Fix an issue where Idl.run() returned False even if there was a change.
If Idl.run() reads multiple messages from the database server, some
may constitute changes and some may not. Changed the way change_seqno
is reset: if a message is not a change, reset change_seqno only to the
value before reading this message, not to the value before reading the
first message.
This will fix the return value in a scenario where some message was a
change and the last one wasn't. The new change_seqno will now be the
value after handling the message with the last change.
