Slim::Music::Import->stillScanning() used to return a string token describing the scan type (full, rescan, playlist), now in the SQLite branch it's only returning 1 or 0.

Old in S::M::I::launchscan():

# Update a DB flag, so the server knows we're scanning.
$class->setIsScanning($scanType);

New in S::Schema::notifyFromScanner:
Slim::Music::Import->setIsScanning(1);

This value is returned to the Settings/Status web page (and other places) to be expanded to the full string. Obviously it fails.
