Problem description: When SAML authentication is used and the user uses a direct URL to login to zabbix and open some speciffic page, after successful login the Monitopring => Dashboards view is displayed, not the vie the URL of which the user used to login.

Steps to reproduce:

1. Login to zabbix and open some speciffic view, like "Zabbix server" host configuration
2. Copy the URL and logout of zabbix
3. Paste the URL in browser. Zabbix login page appears
4. Login using SAML authentication

Result: When the user is logged in the Monitoring => Dashboards view is opened, not the view that should've been opened according to the URL
Expected: the view from the URL should've been opened ("Zabbix server" host configuration)
