properly split query parameter for email (#511)

Service unit query parameter was previously sent as single string like "1,2,3,4", which is not a proper input for forms.ModelMultipleChoiceField.
Synchronous reports already handled this query string properly, so now email reports use the same query parameter parsing for service unit.
