    Related: tdf#122509 prevent access of not existing base format
    
    Call to pFormat->HasPositiveBracketPlaceholder() with nullptr as
    obtained for the not existing nIndex was the immediate cause of
    the crash.
    
    Also obtain the type from the format if found instead of the
    separate GetType() call that again would need to find the format
    first. This clarifies that the other places accessing pFormat
    don't need additional checks because eType isn't UNDEFINED there.
