[Bug] Small bug where you can't delete a secret just after making the backup from a V1 to a V2

[Bastien-Satochip]

How to reproduce the bug:

• Master card : V1 full of secret
• Slave card : V2 initialized but empty

Do a backup from V1 to V2: ok.

Now, the app is open, saying that the backup was done successfully BUT, if you list a secret and want to delete it, you have this popup:

Obviously, the application still think we are using a V1.

To be able to delete the secret, I have to close the application and start it again.

No real big deal but rather a small bug.
