The VM could throw at pushnode and before mpv_free_node_contents, which would have resulted in leaked content. Now this case is handled without leaks. Note: the lua code still leaks on such case, but mp_lua_PITA doesn't have destructors like the JS autofree has, which, specifically here, can do mpv_free_node_contents. So TODO: enhance the lua PITA code to behave more similar to the JS autofree.
