queue.txt: No such file or directory

[Evan Markowitz]

When using /render cancel, the queue.txt file is not found during the grep search for the player, causing for the latter part of the line to make the file contain only a newline ( which might be the cause of #187)

This of course means the queue is empty, and all renders in the queue never occur.

Duplicate of #187.

correct quotes to not carry out shell expansion locally on subcommands, resolves #187 and #188
