When invalid parameters in URL hash tag, dashboard/reports keep reloading infinitely instead of displaying error message #2424

For example, index.php?module=CoreHome&action=index&idSite=7&period=day&date=yesterday#module=Dashboard&action=embeddedIndex&idSite=7&period=day&date=yesterd%3Cspan

the dashboard will reload infinitely instead of displaying the error message returned in the ajax request. The controller should detect that it is a returned error page, and display it below the menu.

(In [4683]) Fixes #2424 - Now there is a proper error message when user tries to reload dashboard for an invalid site (or after being logged out) so we can remove the reload() which causes this bug refs #975
