undefined method hash_md5 for nil:NilClass

Issue Description

/firebase_app_distribution_action.rb:224:in `aab_certs_included?': �[31m[!] undefined method `hash_md5' for nil:NilClass�[0m (NoMethodError)

The build is successfully uploaded to firebase app distribution before this error occurs. The error seems to occur before the build is assigned to the correct groups, however.

Configuration

        release = firebase_app_distribution(
            app: ENV["firebase_app_distribution_app_id"],
            service_credentials_file: "./android/firebase_app_distribution_credentials.json",
            groups: ENV["firebase_app_distribution_groups"],
            android_artifact_type: "AAB",
        )

Thanks for the report and apologies for the bug.

This should be fixed with version 0.9.1. Please let me know if that's not the case.

[nmguse-bighealth]

Thanks for the quick turn around!

I will keep an eye out and reply here if the issue comes up for me again. I'm not sure why but, with no changes in our code, the error went away on subsequent builds, so I unfortunately cannot reproduce this again at the moment. I know I've had this error more than once though (I just recently started pushing builds for a few apps to Firebase app distribution, with this plugin), so I'm guessing this goes away when something like at least one build is submitted to Firebase app distribution successfully.

I'm not sure why but, with no changes in our code, the error went away on subsequent builds,

From my understanding, the code-path, which contained the bug which caused the crash, is only exercised when the first AAB is uploaded for a given app. All subsequent uploads were not affected.
