Daemon silently fails if the default pidfile dir (./tmp/pids) doesn't exist

[thepry]

Hi, I noticed that runner with --daemonize option silently fails if pidfile dir doesn't exist. Which might be an issue, since tmp dir might be empty and when you don't specify pidfile path, it uses ./tmp/pids/good_job.pid and exists the process without any output.

Is this intentional or a bug? I'd suggest using mkdir_p at least for cases when the pidfile wasn't specified. I can put up a pull request if you're okay with that change.

I think that's a bug to silently fail.

But I don't think it should create the directory because that should be a Rails standard thing:

https://github.com/rails/rails/blob/c676398d5ed0afe58ac7547f86547c3e85911af1/railties/lib/rails/generators/rails/app/app_generator.rb#L259

I think simplest option would be to log to stderr that it couldn't write the file (whether that is default value or provided)

@bensheldon sounds good, i'll put up a pull request
