Fix ssl_cert_path does not exist error, and bump version for dev

I got a little bit problem with this cookbook, I keep getting no such method `ssl_cert_path` when I am trying to run `balanced-ci` on my machine, and I realized that it's caused by [renaming of these stuff](`https://github.com/balanced-cookbooks/ci/blob/master/libraries/ci_component_ssl.rb#L130). However, the version of jenkins is not updated, since it's still an old version. I just updated it to `99.1.6`.

I see you guys have odd for development, even for releasing pattern in all these cookbooks, and as mentioned in #1, the version number should be wrong but already released, so I just bumped the number to 1.0.19. I am still not familiar with these repos, so please correct me if I am doing wrong.
