    Change buffer size argument value in call of icalvalue_decode_ical_string()
    
    Since libical 3.0.5 the buffer size argument should include also
    the nul-terminating character, otherwise the function rejects to
    write the decoded data into the passed-in buffer. The code allocates
    one extra character just in case some older libical would write to it.
