[System tests] Increase timeout for upgrade test

[Andrey Sledzinskiy]

Timeout for upgrade should be increased here - checkers.wait_upgrade_is_done(self.env.get_admin_remote(), 1500,
                                      phrase='*** UPGRADE DONE SUCCESSFULLY')

25 minutes isn't enough to upgrade on our CI
