Fix cypress

From https://docs.cypress.io/api/commands/visit#Syntax:

Cypress will prefix the URL with the baseUrl configured in your network options if you've set one.

From cypress.json:

"baseUrl": "http://localhost:8080/exist/apps/doc/"

So cy.visit(‘.’) was causing cypress to request:

http://localhost:8080/exist/apps/doc/.

I’m not able to simulate this request, so I can’t reproduce it to see eXist returning an application/xml content-type header, but it’s clear that removing the period ensures the request goes to the intended URL:

http://localhost:8080/exist/apps/doc/
