reivilibre c775d80b73
Fix a bug introduced in Synapse v1.84.0 where workers do not start up when no instance_map was provided. (#15672)
* Fix #15669: always populate instance map even if it was empty

* Fix some tests

* Fix more tests

* Newsfile

Signed-off-by: Olivier Wilkinson (reivilibre) <oliverw@matrix.org>

* CI fix: don't forget to update apt repository sources before installing olddeps deps

* Add test testing the backwards compatibility
