ALREADY_CONNECTED_TO_READER when trying to connect

[antoinerousseau]

Describe the bug

After some idle time in the iOS simulator, I'm trying to connect with easyConnect and it throws with ALREADY_CONNECTED_TO_READER even though onDidChangeConnectionStatus keeps printing notConnected

To Reproduce
Steps to reproduce the behavior:

1. Activate terminal
2. Wait a few minutes (idle computer)
3. Connect to reader to make a payment in the app

Time (in UTC) when you most recently observed the bug:
Now

Expected behavior
If already connected then don't throw and stay on it, otherwise allow reconnecting.
It should be seamless.

Screenshots

Look at these sequence I'm seeing:

Killing/restarting the app was the only way to unlock the blocked state of the terminal

Hi @antoinerousseau,
Can you confirm that terminal.connectedReader is false at the time you are attempting to reconnect? Any logs you can forward us around the time of the second easyConnect call would be helpful in solving the root issue, as well as any relevant logs happening while you idle.
