Title: Fix extend_query_by_date function if it raises an error

@jone

- Fix extend_query_by_date function if 'datestring' contains a bad date-format.
The function is to extend a query (dict) with a daterange and returns the new
query. If the function can't convert the datestring to a datetime object, it
returns None and the given query is lost.
Now the function returns the untouched query.

- Also fix the bad test for this case.
