Bad SQL query breaks Builder

Context

When a query filters out the_geom column, Builder enters in bad state.

Steps to Reproduce

1. Go to data tab and modify the SQL query.
2. Apply a query selecting only one column. For instance, SELECT name FROM airbnb_listings.

Current Result

The applying query is shown ad infinitum.

The analysis tab is broken.

SQL API queries fail, but the error is neihert captured nor shown.

Expected result

1. An error is shown in the user interface.
2. Analysis tab is properly rendered.

It seems that:

• infinite loop bug was introduced in https://github.com/CartoDB/cartodb/pull/12916 (Oct 2017)
• blank panels bug was introduced in https://github.com/CartoDB/cartodb/pull/13324 (Jan 2018)

After talking to ramiro, this is the table for the UI messages:

	SQL	UI message
1	SELECT x FROM	Error in SQL query: column “x” does not exist
2	SELECT the_geom FROM	The column “the_geom_webmercator” does not exist
3	SELECT the_geom_webmercator FROM	The column “cartodb_id” does not exist
4	SELECT the_geom, the_geom_webmercator FROM	The column “cartodb_id” does not exist
5	SELECT cartodb_id FROM	The column “the_geom_webmercator” does not exist
6	SELECT 1 as x FROM	The column “the_geom_webmercator” does not exist
7	SELECT * FROM wrong_table	Error in SQL query: relation “wrong_table” does not exist

Also no blank panels and infinite loops.

NOTE: tested in version v4.10.20
