    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.
