Sorting FieldValues from get-pnplistitem

[jhugery]

In the PNP.PowerShell module version 1.5 we have noted some strange behavior. When reading in list items to a variable (using Get-PNPListItem), we are not able to sort the variable based on FieldValues (Specifically FileRef). In order to sort the list, we need to assign a new variable to a JSON conversion of the variable's FieldValues, then create another new variable by reading this JSON list back into an array. This final variable can then be sorted. Completely strange behavior. We should be able to sort on the original variables FieldValues field.
