[REF] Extract code to load the contact in tokenCompat

[eileenmcnaughton]

Overview

Extraction of the code to load contact - this is an attempt to break an easy-merge chunk from #21449

Before

getContact is happening during evaluate

After

It is extracted

Technical Details

This isn't quite a pure extraction - it adds a bool for $getAll which allows us to load all when we want them for the token hook but not to otherwise. The other reason why we were loading all return properties is that last time around we got test fails when we didn't. I'm pretty sure that was because the greeting fields weren't being requested so I've added handling to grab those.

Note I also copied the array of return properties to a function since we want to work through them at some point to retrieve using apiv4

I agree with the extraction and so do the unit tests.
