Running gradlew test promps GPG key unlock

[mpkorstanje]

Running ./gradlew test requires unlocking GPG keys, this makes running tests annoying.

Steps to reproduce

1. Create a a GPG key with a password
2. Setup git to sign commits with that GPG key.
3. Run ./gradlew test

Observe:

1. A prompt to unlock the GPG key.
2. OpenTestReportGeneratingListenerTests.includesGitInfoWhenEnabled failing if the prompt is rejected

Deliverables

• Don't create signed commits when testing
