After cancelling the connection to powered off reader, app relaunch is needed for connection.

[pachlava]

Describe the bug There's a state when the reader was found by the app, and the app asks for user confirmation before connecting to a specific reader:

During this, the reader might become powered off. If the user still taps Connect to reader after this, the app will try to connect to the reader, for approximately 45 seconds, before saying it can't connect.

But there's a chance that user will not wait for 45 seconds, and will tap Cancel. Here lies the issue - it looks like the app will still try to connect to the same reader in all subsequent attempts, unless the app is relaunched. Only after that, the app will show the expected Scanning for readers window. An example is in the video below:

To Reproduce

1. Power on the reader
2. Open Settings ~> IPP ~> Manage Card Reader and tap Connect card reader
3. Once the app asks if you'd like to connect to the found reader, power off the reader
4. Tap Connect to reader
5. Make sure the app tries to connect to the reader, and tap Cancel
6. Try reconnecting again ~> it looks like the app will still try to connect to the same reader, instead of staring the process from scratch.

Expected behavior I'd expect the app to show the Scanning for readers window after new connection attempt in step 6.

@pachlava thank you for the report 👏. I put this issue into our maintenance project

I opened a similar issue https://github.com/woocommerce/woocommerce-android/issues/7153 but doesn't require turning off the reader. Feel free to merge the issues if the two are the same issue. Thanks!
