Feature/fga/simplify timeline logic (#6318)

* Sync: delete all previous chunks in case of gappy sync

* Chunk: dont link chunks if we find existing timeline event (keep multiple timeline events in db)

* Timeline : remove some unused code

* Clean and add changelog

* Timeline: set named argument

* Timeline: avoid restarting the timeline when there is a CancellationException due to permalink

* Timeline: add migration to clean up old (broken) chunks

* Update matrix-sdk-android/src/main/java/org/matrix/android/sdk/internal/database/migration/MigrateSessionTo030.kt

Co-authored-by: Benoit Marty <benoitm@matrix.org>

* Timeline: try to fix test

* ignoring broken instrumentation test in order to release
