TCK is using yearMonthDuration/dayTimeDuration/dateTime typeRefs

[StrayAlien]

A number of tests are using the above typeRefs but, as far as I know, they are not valid FEEL types.

Perhaps some legacy?

Should we perhaps just do a blanket change to correct them to their proper FEEL types?

Discussed on the meeting - if some types are not valid FEEL types, we should fix those.
