Running RemoveAllAsync after creating instance

[balonmilan]

problem

When I run as first method after initializaion, it does not work, because Pairs property is empty.

NullModemEmulatorManager manager = new();
var ret = await manager.RemoveAllAsync(); //returns true, but pairs is empty, so nothing is removed

workaround

As workaround, I must first run ListAsync():

NullModemEmulatorManager manager = new();
await manager.ListAsync();
var ret = await manager.RemoveAllAsync();

Yeah, you should called ListAsync first.
