Multisite command sometimes thinks it has run, but hasn't.

Bug description

If you end up in a situation where you have 'multisite' => true in your config file (but do no other multisite steps) and then you run php please multisite, it'll tell you:

ERROR  Command may have already been run. Site directories for site [default] already exist!  

That's not true though. There are no directories. The issue is that $this->siteHandle is null at this point, so the path it checks is actually the parent.

How to reproduce

• Add 'multisite' => true to your config.
• Run please multisite
