Fix kill when user differs to process owner

[joeholdcroft]

When running Fresque on my Vagrant box with the user set to www-data but running the commands as vagrant, I noticed that the stop command did not work.

It didn't report an error, but it did not output the green "Done" text next to each stopped worker. The output looked something like:

----------------
Stopping workers
----------------
Workers list
  1) vagrant:8048:dispatched_orders, started 1 day and 2 hours ago
  2) vagrant:8039:new_orders, started 1 day and 2 hours ago
all) Stop all workers

Worker to stop: all
stopping 8048 ... 
stopping 8039 ... 

I copied some code for running the command as another user from the start method. It might want some abstraction to avoid the repetition, but I wasn't sure what other commands might be affected.
