EnvironmentHelper tries unauthorized access to .walletwasabi/client every run on iOS device
This causes problems when people read back the logs to us even though the error is benign.

Seems this could be resolved by injecting an up-to-date EnvironmentHelper that accounts for iOS, but unfortunately that's part of Wasabi as is. These two EnsureBackwardsCompatibility functions throw even though we never supported 1.1.5 through 1.1.7 so they're really safe to ignore in Chaincase.

This can probably continue to be ignored it's more a nuisance than an actual problem.
