Muliple unit test fails if gitconfig has commit.gpgsign=true

[rickard-von-essen]

Trying to run ./gradlew clean test --no-build-cache fails on multiple unit test if ~/.gitconfig contains:

[commit]
   gpgsign = true

IMHO the fix for this is to have a canned gitconfig that unit tests uses to avoid depending on the devs setup.

These tests fails:

• GitRatchetGradleTest. [1] 0
• GitRatchetGradleTest. [1] 0
• LicenseHeaderTest. ratchetFrom()
• LicenseHeaderTest. ratchetFromButUpdateFalse()

Example stacktrace:
