There's no need to keep our injected methods and signal connections around when the startup animation has completed.
…mation During startup animation the shell may receive a monitors-changed event, in this case the startup animation events are never triggered because the background loaded signal is never emitted. To prevent this, re-implement the update background code during the layout _prepareStartupAnimation so that we can catch monitor update events and react accordingly.

Especially under X11 we may get "monitors-changed" event while the startup animation is in progress, while some of them were addressed by !2269 (merged), we still have an issue happening:
GNOME shell is preparing the animation and awaiting for bg changes
Monitors are changed, during this phase we destroy the current background managers
=> The "loaded" signals we were waiting for, won't ever happen
This implies that we are stuck in
await this._updateBackgrounds(); and thus we keep staying in broken mode.Ubuntu issue is https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/2019751 it can be simulated with https://gitlab.gnome.org/3v1n0/gnome-shell/-/snippets/5749
