tests: use fn_git_commit in test-encoding.t In c4849b2dab87, the "commit" function was extracted into a testutil for re-use. However, test-encoding.t was skipped over in that changeset, as I was seeing unexplained test failures. Since those test failures have now been explained (and fixed), this changeset performs the same extraction on test-encoding.t as was done on all the other tests. The version of fn_git_commit that was used in testutil redirected all output (including errors) to /dev/null, which didn't match the expectations of this test. The test utility functions for commit/tag now no longer throw away error output, instead leaving it to individual tests to decide if error output should be ignored.
