Fix test_allowed_event_list, MariadbGtidEvent added (julien-duponchelle#375)

Currently the `TestBasicBinLogStreamReader::test_allowed_event_list` test fails,
with the actual number being one more than the expected number.

The reason for that is the recent addition of `MariadbGtidEvent` commit
7fd706d.

This commit adapts the expected numbers in the test to reflect that change.
