💡 Description

• Initial commit adding UITest to detect cookie problems
• Add test HTML page with cookies, simulating login and other cookies
• Add test that loads test page logs in and checks state then relaunch the app and check that the state is Log in still.
  Next step is to make it fail. I tried reverting the fix for the latest cookie issue and is not enough to make the test fail. I think we need to do more steps like add a new tab to force the select tab flow.

@isabelrios In this step I'm trying to open a few tabs to go through the process of creating a tab, selecting etc, which has caused cookie issues in the past, but the test is not passing locally because it is not typing the address I'm not sure what I'm missing
