Show a tile for an unloaded predecessor room if it has via_servers (#10483)
* Improve typing in constructor of RoomPermalinkCreator

* Provide via servers if present when navigating to predecessor room from Advanced Room Settings

* Show an error tile when the predecessor room is not found

* Test for MatrixToPermalinkConstructor.forRoom

* Test for MatrixToPermalinkConstructor.forEvent

* Display a tile for predecessor event if it contains via servers

* Fix missing case where event id is provided as well as via servers

* Refactor RoomPredecessor tests

* Return lost filterConsole to its home

* Comments for IState in AdvancedRoomSettingsTab

* Explain why we might render a tile even without prevRoom

* Guess the old room's via servers if they are not provided

* Fix TypeScript errors

* Adjust regular expression (hopefully) to avoid potential catastrophic backtracking

* Another attempt at avoiding super-liner regex performance

* Tests for guessServerNameFromRoomId and better implementation

* Further attempt to prevent backtracking
