[BUGFIX] Restore record date fields for all users

Prior to the introduction of the column selector
in #84184, did a boolean flag "$addDateFields"
define whether record date fields (tstamp and
crdate) should be added to the available field list.

Actually, those fields were always added, because
all usages of the corresponding method set either
"$addDateFields" or "$dontCheckUser" to TRUE.

This fact is now restored by always adding the
mentioned fields.
