XProfile: More consistent cache behavior when fetching user data.

  • Inside of a profile group loop (BP_XProfile_Group::get()), don't fetch user data when pulling up BP_XProfile_Field objects. In the absence of finer-grained information about users, fetching a field object grabs the data associated with the logged-in user. But in many cases, the logged-in user is irrelevant to the fields being looped over, so there's no benefit to pulling up this data. (When necessary - fetch_data - the data is queried separately, later in the get() method.)
  • When caching database misses for a data query (because the specifed user doesn't have anything filled in for the given field), store the field_id and user_id properties on the cached object. This ensures that values are properly associated with their fields when being displayed.

These changes resolve an issue where cached data for the logged-in user
can be shown erroneously on another user's profile, when the other user
doesn't have a value for a given field.

Props m_uysl, r-a-y.
See #6091. Fixes #7401.
