A stray ast_cdr_setvar was missed in cdr_mysql (silly addons). This has now
been refactored to not set the property, as the property would have been set
on a run-time object that was already dispatched to the backend. The module
simply remembers the value it wanted to set and writes it to MySQL later
in the processing.
