[BT] Sending multiple files through BT doesn't work realiably

@attah

It would be nice if you were more clear on whether it was to or from SFOS.

actually I didn’t need to add that info because SFOS doesn’t allow you to share multiple files at once without my patch and even then, it’s not working, here’s a bug:

[4.5.0.16] NextCloud and Bluetooth sharing api doesn't accept multiple resources

I would have thought it was due to this uninitialized boolean (and perhaps it may still be): But my SeaPrint sharing plugin correctly does not show up when multiple files are shared. So it sure looks like the plugins register with multi-file capability and doesn’t deliver on it.
