Cannot turn on Bluetooth after turning it off during pairing

Hi,

I found a minor and very specific issue in the Bluetooth GUI. The requirement is to have a smartphone with enabled Bluetooth. Here are the steps to reproduce the case:

1. You need a phone with enabled bluetooth around.
2. Open Settings
3. Go to Bluetooth
4. Click pair
5. Very fast click the toggle to turn off the Bluetooth.
6. Try to turn on the Bluetooth again.

Expected result: turn on the Bluetooth
Actual result: Can't turn on the Bluetooth

I have seen this issue with AGL Grumpy Guppy v6.99.2 on Raspberry Pi 3B and 3B+ using the built-in Bluetooth.

Best regards, Leon
