fix(cli): remedy regression in start cmd

This commit remedies a regression noticed by user @notkvwu in #493,
which results in 'komorebic start' failing, due to an empty ArgumentList
being passed to the PS Start-Process command.

This has been fixed by ensuring that the ArgumentList is only passed
when the user has specified flags on the start command.

fix #493
