Wrong device label in startup

[mehdideveloper]

SigDigger's main window title is always set to one of my SDRs on startup, but I think this is a UI bug, because it does not always work as expected. For example: 1- I connect RTL SDR to laptop and open SigDigger, but still shows "AirSpy" in the main window title (this is in the startup, before selecting RTL from settings and running it). In this scenario, AirSpy is not connected to the laptop. 2- I don't connect any SDRs to laptop, and still see the last SDR's name in the window title
