MDL-63960 dataprivacy: Do not perform strict type checks for id

Browse Source 
When inherit is specified in the data registry it is stored as a
string and we cannot perform a strict comparison with it.

We should still compare strict comparison checks against null, or false,
but not for the NOTSET (0) or INHERIT values (-1).
