IAR Frontend - OAuth login fails in private mode

3rd party cookies are now disabled in chrome by default when using private/incognito mode. They also seem to be frequently disabled by anyone attempting to avoid tracking cookies.

This causes the google OAuth2 login to fail.

Possible Solutions (See this github issue):

• Catch the error and prompt the user to enable cookies (or add an exception for the google accounts cookie)
• Implement server side OAuth
