Subject: [PATCH] track import: get extension from file name, not URI

When importing tracks from nextcloud, the URI for a file may be something like

content://org.nextcloud.documents/tree/7keh3ot7zmiaxecoktv6bfn6gdygt2lg%2F707/document/7keh3ot7zmiaxecoktv6bfn6gdygt2lg%2F745

The URI contains no ".", so getExtension() would return the whole URI as the extension, resulting in an "Unsupported file format" error.

To fix this, also pass DocumentFile.getName() to the ImportWorker.
