TypeError: undefined is not a function in RedisClient

Not sure which command it's trying to send, but possibly ping. 324cad6 seemed to fix my issues at first, but then I got this:

prerender_1 | /app/node_modules/prerender-redis-cache/node_modules/redis/index.js:959
prerender_1 |             return this.send_command(command, to_array(arguments));
prerender_1 |                         ^
prerender_1 | TypeError: undefined is not a function

I don't have time to investigate at the moment, so I'm opening this issue.

Hey @aalin - Thanks for your commits. For the time being I'm going to rollback but keep this open as I liked the ping fix for the disconnect to keep connection alive. Just don't want people pulling a broken package from NPM. J
