  Fix Background within a Macro for FreePBX.
  If the single digit DTMF is an extension in the specified context, then
  go there and signal no DTMF.  Otherwise, we should exit with that DTMF.
  If we're in Macro, we'll exit and seek that DTMF as the beginning of an
  extension in the Macro's calling context.  If we're not in Macro, then
  we'll simply seek that extension in the calling context.  Previously,
  someone complained about the behavior as it related to the interior of a
  Gosub routine, and the fix (#14011) inadvertently broke FreePBX
  (#14940).  This change should fix both of these situations, but with the
  possible incompatibility that if a single digit extension does not exist
  (but a longer extension COULD have matched), it would have previously
  gone immediately to the "i" extension, but will now need to wait for a
  timeout.
