Switch Layout of Visualisation widgets in dashboards

[atharvai]

Issue Summary

Visualisation widgets in dashboards have Query name for title and visualisation name is small. I feel like on a dashbaord the title of the widget should be the visualisation name. the query name and description should be smaller

On a dashboard it is hard to find visualisations if there are multiple charts from same query. the focus should be on visualisation name

From looking at the usage in the SaaS version of Redash, I can see that only 15% of visualizations have a title, but almost 50% of visualizations that get placed on dashboards have a title.

Still it means that in 50% of the cases, we will see "Chart" or "Table" as the main title of the widget...

Maybe the logic should be:

1. If the visualization has a custom name, then use the visualization name and add query as the small title.
2. If the visualization has a default name, then use the query name.

WDYT?

I agree, that makes sense.
