Username changes should be visible immediately (allUsers should prefer certificates over CSRs)

[leblowl]

displayableCurrentChannelMessages selector uses allUsers to select the username for a message. If CSRs have precedence over certs, then it could display an invalid/old username for that user.

allUsers is also used in displayMessageNotificationSaga and showNotificationSaga to get the username for a notification.

This relates to which username will show when a user has a pending request to change their username: their new requested name or their existing name.

@holmesworcester Do you have an idea for how to move forward with this?

Should we show the registered username until a pending username is registered? Or should we show a pending username if there is one? I think currently, we are doing the latter.

Also do you think we can address this later? To me, it doesn't seem like it should hold up the release necessarily, but curious to hear your thoughts.

I think showing the pending username is correct. If that's the current behavior and there aren't other questions let's close this.

[leblowl]

I'm not sure if it is the current behavior. Looking at the code again, it looks like it prefers the cert:

quiet/packages/state-manager/src/sagas/users/users.selectors.ts

Lines 85 to 96 in f94151b

	Object.keys(certs).map(pubKey => {
	users[pubKey] = {
	...certs[pubKey],
	isRegistered: true,
	isDuplicated: false,
	pubKey,
	}
	console.log('Unregistered Debug - allUsers selector - certs - user', users[pubKey])
	})
	Object.keys(csrs).map(pubKey => {
	if (users[pubKey]) return

Then let's leave it open but move it out of this sprint.

I renamed the issue to make it clear what the product-level impact is.

Sounds good, thanks!
