Stopped spamming of debug messages during attended transfer.

While autoservice is running and servicing a channel the callid is being stored
and removed in the thread's local storage for each iteration of the thread loop.
If debug was set to a sufficient level the log file would be spammed with callid
thread local storage debug messages.

Added a new function that checks to see if the callid to be stored is different
than what is already contained (if anything).  If it is different then
store/replace and log, otherwise just leave as is.  Also made it so all logging
of debug messages pertaining to the callid thread storage outputs only when
TEST_FRAMEWORK is defined.
