🐛 Fix Alexa import status error message retrieval

[sadlowskij]

Proposed Changes

Currently Jovo assumes ImportStatus.skill.resources to never have a length > 1. Therefore, if the array is not empty, it tries to look the error property in the first element of resources. In reality however, the resources can consist of >1 elements, where the error property might not be present in the first element. This leads to the folowing error:

This is caused by this expression: status.skill.resources[0].errors.length.

This is the resources property in my test, when I set privacyPolicyUrl to abc to test this behaviour:

[
    {
        "action": "UPDATE",
        "info": [
            {
                "message": "No change in resource and its dependencies detected. Resource version is up to date with imported package version. Update skipped."
            }
        ],
        "name": "InteractionModel.en-US",
        "status": "SKIPPED"
    },
    {
        "action": "UPDATE",
        "errors": [
            {
                "message": "String instance with value \"abc\" at property path \"$.manifest.privacyAndCompliance.locales.en-US.privacyPolicyUrl\" is not a valid URL."
            }
        ],
        "name": "Manifest",
        "status": "FAILED"
    }
]

Here you can see the error property being present on resources[1] instead of resources[0].

Therefore I changed the type of resources to a normal array instead of a tuple with one element. Also it now looks up the element with an error present instead of assuming it to be the first element.

With these changes you get the following output in the cli:
