resolve_bootstrap_node assert hit

[zoff99]

c-toxcore/toxcore/tox.c

Line 1018 in b8aa21c

assert(*root != nullptr);

i have hit this assert in resolve_bootstrap_node on a box with DNS lookup timeouts.
do we need to fix something here?

Going through

c-toxcore/toxcore/network.c

Line 1768 in b8aa21c

int32_t net_getipport(const char *node, IP_Port **res, int tox_type)

it might be that

c-toxcore/toxcore/network.c

Lines 1799 to 1800 in b8aa21c

	const int ret = getaddrinfo(node, nullptr, nullptr, &infos);
	*res = nullptr;

does not return an error, but not returning a ipv4 or ipv6 address
leading to

c-toxcore/toxcore/network.c

Lines 1825 to 1828 in b8aa21c

	if (count == 0) {
	freeaddrinfo(infos);
	return 0;
	}

it would really help if we knew which return you hit in net_getipport()
