[BUGFIX] Check correct setting on extension upload

With #82368, the Configuration API is used in the Extension Manager to
check specific configuration.

However, for automatic extension installation the wrong setting was
checked. This patch now uses the correct setting, fixing an issue with
extensions not getting installed after upload.
