When creating a visualisation after running a query the query results are deleted

[ifeldmanAtlassian]

We are testing the latest stable version of redash (6.0.0+b10818 (7fa6665)
Found a regression when creating a new visualization, to reproduce:
0. Open a new browser tab and log into redash

1. Run a query
2. Create a new visualization
3. The X & Y drop downs are empty
4. When you cancel the visualization creation you see that the query results disappeared

Note - the issue occurs only when you run redash for the first time on a new session

The issue isn't with a specific visualization, but with the query losing reference to the query result.

I think the issue happens because we don't take reference to the query result from the UI, so when first saving the query it gets saved without a query result reference (latest_query_data_id):

redash/redash/handlers/queries.py

Lines 213 to 214 in 933dd75

	for field in ['id', 'created_at', 'api_key', 'visualizations', 'latest_query_data', 'last_modified_by']:
	query_def.pop(field, None)
