The consent count report should not include all consents without date

[Nicklas Nordborg]

When running the "Consent count report" wizard with a date filter it will always include all consents without a date. This will cause some of the numbers to be less usable. Particularly the numbers for "No" and "Not asked" since they tend lack a date more often than "Yes".

When a date filter is used and a consent date is missing, the registration date should be used as the filter criteria. It is important to note that the registration date should not be used as a replacement for the consent date when counting since that would cause all "missing date" columns to be 0.

(In [4177]) Fixes #916: The consent count report should not include all consents without date

Set a filterDate that is either the consent date or the registration date. Then use that date to check if a specific case/blood item should be included in the current statistics or not.
