SyncSource: better error message for incomplete config 

The file backend refuses to create a source if backendFormat is unset.
This was reported as "<source>: backend 'file' not supported",
which was confusing because the backend was in fact supported.

Now the error message is "<source>: backend 'file' not supported or
not fully configured (format '<format>')".
