On templates validation stage vmalert does not acutally send queries, so for complex chained expression validation may fail. To avoid this, we add a blank sample in response so validation can pass successfully. Later, during the rule execution, stub will be replaced with real `query` function. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/989
