remove elements of flaky e2e test
This test only checks 'undo' in the code editor and then checks if the query builder is present. The test is timing out when looking for the query builder. There should be a second test to check if undo works in the query builder so I'm removing the query builder check. I will add an issue to create a test for 'undo' in the query builder.
