NimBLEDevice cannot be re-initialized after call to deinit()

When NimBLEDevice::init("") is called after a call to NimBLEDevice::deinit(), the reinitialization fails and BLE scans cannot take place.

Thanks, it's been a while since I tested this. I'll have a look.

Just pushed a fix for this, reopen if you have anymore issues.

Edit: @thorrak, forgot to say thanks for the beer! Really appreciated.
