SQL Integration Tests for the guardian class too.

Removes restricted dashboards from search result.

Breaks some stuff like selected dash in the search result.
In dashboard search, if the user is not searching then the result is
returned as a tree structure. No ACL's or user group ux yet.

Explains that you need to clone the grafana repo if you have not done that already.

When table data returns a column with the value 0, it should not ignore
it. This change checks for undefined instead of if the value is truthy.

Fixes #8531

dashboard_history: fix for scenario where reverted dashbord has different title and url must change not just route reload

dasboard_history: fixed disabled attribute so it works both by disabling and fixing style, no need for disabled class and disabled attribute

dasboard_history: fixed json diff so only dashbord is compared and not the whole dashboard revision object (message and restoreFrom etc was showing up in json diff)
