incorrect type for GetPhonebookEntryUID

[rainmang]

When running the Test: TestPhonebook() with my FritzBox 7590 using the current firmware, the test crashes inside the following function GetPhonebookEntryUID while deserealizing the XML PhoneBookEntry.
In contacts.cs the variable uniqueidField is defined as a byte.

In my case the value of the uniqueid was 41418, so trying to store that value in a byte caused the error. After changing the type to uint everything worked as expected.
The current AVM document (https://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/x_contactSCPD.pdf) Page 18 shows that the variable "PhonebookEntryUniqueID" should be defined as ui4.
