Plugin modification for redmine 3.4.2 on ruby 2.4

[wlk-cz]

I am not ruby specialist, but I spend last two days learning this language to get this plugin work. I have to change array association on many places from @settings[:client_id] to @settings['client_id'] for all plugin parameters. Can someone explain me, why? Without this modification the plugin didn't store settings and didn't show google login button.

Thank you for digging this, it works for my newly install Redmine :)

However, the Google Login button doesn't show...
