fix: Make sure sessions are cleared between tests

From the discussion so we can continue here:

I would prefer a try/catch or error catch somewhere in case this test is restarted. If we always logout before running this entire test (which is really checking the default state of cypress and nextcloud) does not make sense anymore. :)

Maybe do that on fail ?

@susnux

This is just run once before, so it just ensures a consistent test environment. So it ensures it does not matter if users.cy.ts is run first or this one.

I think we want to test the login works, so we assume we are logged out on the first test Login and see the default files list so we can enforce this initial state to properly test this scenario, or am I missing something?

@skjnldsv

No, the issue is about the logic.
With independent sessions for each test, we should not have to logout. Manually adding this will circumvent the actual behaviour of those cypress tests :)

After thought, I forgot we were not using session isolation.
So it does make sense to have this in! 👍

Thank you :)
