Allow creating new config entries

mpapis · Michal Papis · commit 1ac6ce302e20 · 2019-03-25T13:57:41.000+01:00
Git 2.1.2 introduced setting values even if they did not previously exist.
The git-ruby library keeps compatibility with Git 1.6, this fixes the
problem of older versions not being able to create new values.
