Updating from an old version to 1.0(22) causes a crash

[jens-concordium]

Bug Description If you have an old version of the mobile wallet installed, e.g. 1.0(6) and then update 1.0(22), the app will crash upon reopening it. On iOS 14.7 it will give a pop-up saying that the app has crashed and on iOS 15 the app will show for a split second, before just disappearing without any pop-ups.

This might be related to the iOS 15 SDK upgrade.

Steps to Reproduce

• Install an old version of the app, e.g. 1.0(6), set it up and maybe populate it with a bit of data.
• Update to 1.0(22) without uninstalling the old version first.
• Try to open the app, and notice how it crashes.

Expected Result

• The app opens after update without problems.

Actual Result

• The app cannot be opened after an update to 1.0(22), because it crashes immediately.

Versions

• Software Version: 1.0(22)
• OS: iOS 14.7 and 15

This works on iOS 15 now at least. Probably good to test on iOS 14 as well, @concordium-cl.

Checked on iOS 14.7.1.

Fixed in 1.0.23.
