`git-secrets --install` test failures without code changes

[sparr]

I believe that all tests passed when I last contributed to this repo, both before and after my change. I have confirmed that the following failure happens now with the current master branch and with commit b9e96b3 prior to the last change. I suspect this could be caused by some change to my bash, git, grep, etc, but I haven't been able to narrow it down yet.

 ✗ Overwrites hooks if -f is given
   (in test file test/git-secrets.bats, line 147)
     `[ $status -eq 0 ]' failed
   Initialized empty Git repository in /tmp/test-repo/.git/
   /home/clrnc/src/git-secrets
   /tmp/test-repo
   /tmp/test-repo
 ✓ installs hooks for repo with Debian style directories
 ✗ installs hooks to template directory
   (in test file test/git-secrets.bats, line 164)
     `[ $status -eq 0 ]' failed
   Initialized empty Git repository in /tmp/test-repo/.git/
   /home/clrnc/src/git-secrets
   /tmp/test-repo

The failure on line 147 which tests line 146 is late. There's actually a NZEC on line 145 which isn't currently being tested for.

Both failures are related to git-secrets --install
