[iOS] Broken rule should yield "open", not "false"

[chrloch]

Description

When a rule is broken (e.g. features an undefined variable), the verifier app on iOS yields a failed status for this rule.

Expected behaviour

The status of the rule should be OPEN (as it is in the Android version)

Steps to reproduce the issue

This can be reproduced scanning a valid vaccination DCC and verifying for Switzerland.
VR-CH-0004 and VR-CH-0006 contain a reference to "var":"external.validationClockAtStartOfDay" which does not exist.

Technical details

Reproduced with ACC backend

@chrloch any idea how to test this issueon an other way? The reference to "var":"external.validationClockAtStartOfDay" doesn't exist in the Switzerland Rules (on ACC)

[chrloch]

I can create a broken rule for the DX country again.

[kerstin-oppermann-tsi]

This would be good when @ihorkhomyak or @ivlasov implemented a fix for that issue.

[kerstin-oppermann-tsi]

@chrloch can you retest this issue or provide a broken rule for testing

[chrloch]

I don't have an iOS device but I have created a broken rule to become effective in two days:
[rule service acc] /rules/DX/2b77f485a984ae9fb52a14b8ba4bf52948f9948c6a6bf3b3d0c15f052b7b6263

Seems issue is fixed now with verifier 1.2.3.1(12)
