RESTBasicAuth isn't being enabled in KTD despite issue #91

I've noticed in KTD that RESTBasicAuth isn't being set. I think this is always the case, but I notice it most often when I'm using reset_all when I'm the kohadev-koha user. It says the following:

Running [koha-mysql kohadev -e 'UPDATE systempreferences SET value="1" WHERE variable="RESTBasicAuth"']... sh: 1: koha-mysql: not found

But all other reset commands work.
