GetAttachedPropertyValues not returning empty always_include property values

[MaxSchaefer]

Describe the bug

If a property has the always_include flag but it empty, the property does not get returned by GetAttachedPropertyValues. Thats incorrect. Property values of properties should be shown if they are not empty or in the always_include list.

Describe how to produce the bug

• Create a property
• Dont create a property value
• Set this property to the property view always_include list of an arbitrary patient or task
• Call GetAttachedPropertyValues for this arbitrary patient or task
• Your property is not there
• Attach a property value
• Your property is there

I will retry with other Value types

I've added a matrix test, that tests all {Task, Patient} x {Number, Text, ...} combinations: #875

A different test is failing due to a side effect fixed in another PR of mine, but the new tests all pass.

From what I can see this is not reproducible.
