Remove old real time trip updates from Raptor timetables

[t2gran]

Summary

The existing code only remove real time trip updates with modified stop-patterns, not added trips(NeTEx ExtraJourney). If an ExtraJourney is canceled, the first update is not removed.

Issue

This is a follow up on #7052. We would like to do this in multiple PRs to minimize risk.

Unit tests

There is very few unit-tests testing the business rules in play here, none of the existing tests broke when this code was changed. I have not added new test - I want to replace this logic and in that case the test is not possible to reuse.

Documentation

🟥 No doc added.

Changelog

🟥 This is a follow up on #7052, it should be enough to mention the main issue/PR in the change log.

Bumping the serialization version id

🟥 Not needed-
