Data Picker not presented in some criteria in cohort explorer

[birgerhaarbrandt]

For elements of type DV_DATE and DV_DATETIME, we expect there to be a date picker as shown in this example:

However, this is not showing up reliably for all data fields:

Expected result is the correct and consistent rendering of the date picker whenever a data or date time needs to be chosen. The data picker should also show the right level of detail (only dates when required and full date time including minutes and seconds if required).
