Filter isn't applied to word cloud chart on a dashboard

[bryanck]

If you apply a filter to a dashboard that has a word cloud chart on it, the word cloud chart will not be filtered.

Expected results

When a filter is applied to a dashboard, the word cloud chart should have the filter applied as well.

Actual results

The filter is not applied and the query sent to the backend does not include the filter. However, if you click on the ellipsis menu and "Explore" the word cloud chart in the chart editor, then the filter shows up and is applied.

How to reproduce the bug

1. Create a filter box
2. Create a word cloud chart that uses the same datasource as the filter box
3. Create a dashboard and place the filter box and the word cloud chart on it.
4. Apply a filter using the filter box.
5. The filter is not applied to the word cloud chart

Environment

• superset version: 0.37.0 RC 2

I reproduced the problem. I have a working solution, but need to add proper tests to ensure this doesn't happen again. The fix will unfortunately probably need to trigger rc3.
