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 Co-authored-by: ganfra <francoisg@element.io> Co-authored-by: Benoit Marty <benoitm@matrix.org> Co-authored-by: Adam Brown <adampsbrown@gmail.com>
