PHP 8.1: only the first importer is loaded

[kraftbj]

I haven't dug into this, but I assume it is related to the singleton change in master for PHP 8.2. Whenever using the plugin, the Delicious importer is always used.

1. Visit Tools->Import
2. Try to import from TripIt
3. Error that we don't have a Delicious account setup.

Delete the Delicious file and repeat... same but now says FitBit.

Delete all except TripIt, it works fine.

Just realized that the server I'm running the importer on is still on 8.1.
