Prevent repeated dialog toast messages

[theronakpatel]

When there is an error, Nextcloud typically generates many repeated messages to the user.
We can at least modify the nextcloud-dialogs library to not show a message already on screen.
Alternatively, identify a few cases (like storage full) and buffer those on the component generating the alert.

Yeah that should be done. I don't think it's the job of the lib to deduplicate, because it can not know if that is needed or not. Maybe the user pressed another button and again receives a "No permissions" error. So it should be triggered again.

Storage notification should therefore be fixed in the files app.

@nickvergessen but cant we hide previous one first then show new notification!

[nickvergessen]

yeah the code that creates it can do that already.
