NullPointerException when git repo is brand new (no commits) #57

[ERROR] Failed to execute goal pl.project13.maven:git-commit-id-plugin:2.1.2:revision (default) on project abc: Execution default of goal pl.project13.maven:git-commit-id-plugin:2.1.2:revision failed. NullPointerException -> [Help 1]

This is on 2.1.2, 2.1.3 didn't make it to me yet. Maybe you don't care. Pretty obscure use-case :-) Feel free to close wont-fix if you like. Just wanted to document it.
