GST_DEBUG_BIN_TO_DOT_FILE() would cause a segfault whenever it encountered an
element's caps that had a field value being NULL. Such fields are successfully
handled e.g. by GST_*_OBJECT(), and with this patch so does
GST_DEBUG_BIN_TO_DOT_FILE(). Even if string fields with a NULL value are
not supposed to be valid in caps, such caps can be created.
