fix RULE_YUMOBS message

python3: /builddir/build/BUILD/libdnf-0.22.0/libdnf/transaction/private/../../utils/tinyformat/tinyformat.hpp:629: const char* tinyformat::detail::streamStateFromFormat(std::ostream&, bool&, bool&, int&, const char*, const tinyformat::detail::FormatArg*, int&, int): Assertion `0 && "tinyformat: Not enough conversion specifiers in format string"' failed.
Aborted (core dumped)

libdnf doesn't give any useful message, but manually comparing messages
and arguments helped to find this.
