A .gitignore will cause git2consul crash when ignore_file_extension" : true

[russellyou]

{"name":"git2consul","hostname":"***","pid":9004,"level":50,"msg":"Some consul updates failed:\nFailed to write key due to Error: consul: kv.set: key required","time":"2017-09-13T23:59:24.308Z","v":0}

I can see git2consul read key as empty after removing file extension of .gitignore
