Fixing error when using more than one helper

When placing more than one helper in the test/integration/helpers
directory I was receiving the following error:


    /tmp/busser/gems/gems/busser-0.6.0/lib/busser/command/deserialize.rb:46:in `Integer': invalid value for Integer(): "0664echo" (ArgumentError)

            from /tmp/busser/gems/bin/busser:23:in `<main>'

When I add the semicolon to helperfiles line I can use multiple helpers without an error.

I was only able to test again 1.0.0, but when I did it seemed to work.
