[BUG] Guild Member Fetching on Startup fails (sometimes)

[zekroTJA]

Sometimes on startup, only a fraction of the present guilds are collected for member fetching on ready event.

That might be because the ready listener in the Ready handler occasionally fires before the ready handler of dgrs which caches guilds received on ready event.

The error might be introduced here:

shinpuru/internal/listeners/ready.go

Lines 81 to 83 in 1a361eb

	guilds, err := l.st.Guilds()
	if err != nil {
	logrus.WithError(err).Error("READY :: failed getting guilds")

It might be fixed by using the guilds from the ready event there as well independent of the currently cached guilds, because the list of guilds are the same for both event handlers.
