Fix null my_info handling for swaps

[CharlVS]

Summary

• handle null my_info when parsing swaps
• make Swap.myInfo nullable throughout the app
• guard UI and sort logic when myInfo is absent

Testing

• flutter pub get --offline --enforce-lockfile (fails: version solving failed)
• flutter analyze --no-pub (fails: analysis server exit)
• dart format -o none lib/blocs/trading_entities_bloc.dart lib/model/swap.dart lib/views/dex/dex_helpers.dart lib/views/dex/entities_list/history/history_item.dart lib/views/dex/entities_list/history/swap_history_sort_mixin.dart lib/views/dex/entities_list/in_progress/in_progress_item.dart lib/views/dex/entities_list/in_progress/in_progress_list.dart lib/views/dex/entity_details/swap/swap_details.dart lib/views/dex/entity_details/swap/swap_details_step_list.dart

@CharlVS Maybe it would be a good idea to add a separate test (or tests) under test_units to deserialize the response of getMyRecentSwaps and create different test cases where my_info and other parameters are set to null. Just to be sure we cover as many of those cases as possible.

What do you think? Is it worth doing?

[DeckerSU]

LGTM.

However I just want to mention that there are plenty of places where the GUI relies on kdf. For example, if events contains null, this expression List<Map<String, dynamic>>.from(json['events']) will fail as well, etc.

Also, this isn’t related to these changes, but I noticed that in this build (not sure in which commit it was introduced earlier) on the Windows platform, if a user enters an incorrect wallet password, it doesn’t say "Invalid password" or anything similar. Instead, it responds with "Invalid parameters provided to wallet," which can be confusing. Just letting you know here - I’ll probably create a separate issue for this.

[smk762]

If you could please supply the steps to replicate (i.e. spawn a swap with nulls), I'm happy to confirm testing. I was unable to see a related issue which might reveal this.

Equally content to approve based on Decker's tests, as he first reported the problem and would be best placed to confirm it has been resolved.

[DeckerSU]

I guess we can merge this into dev, since the root of the issue is now resolved and KW can correctly handle null in my_info.
