OF-2833: Fix serialization of User when date properties are null
Since OF-2768, various 'date'-based properties of the User class are more likely to be null (especially in context of LDAP/AD).
In this commit, a serialization issue is fixed that is triggered by these null-values.
OF-2832: When merging data, handle null values
When merging VCard data, if either the left-hand or right-hand side data is null, simply return the other bit. The code already did this in one direction, but now does it for the other direction too.
This allows a VCard for a non-existing user to be set (which fixes setting avatars for MUC rooms).
