CloudWatch: Avoid exception while accessing results (#17283)

Browse Source 
When accessing the `series` property of query results, if a query is
hidden, an exception is thrown. This is caused by lack of checks to
verify that the query result exists before accessing the `series`
property.

Closes #17112
