WPB-18159 [iOS] NSE: connection requests not processed properly

Issue

Context: When receiving a push notification for a connection request, it's not processed correctly when going to to the foreground (request doesn't show up). Another issue is when ignoring a connection request from web client, app shows a notification saying connection was accepted.

Causes: Legacy logic for connections request processing was not correctly ported to new code (see ConnectionRequestStrategy). Also when receiving a push notification we were not properly discarding the connection statuses we don't want to display notifications for.

Solutions: Port legacy code to properly process the connection requests. Add validation criteria in NSE to only handle .pending or .accepted connection statuses.

Testing

Have another user send a connection request
in iOS app, wait for the push notification, tap on it, when going to the foreground, it should correctly show up in the conversation list.
for second bug, same process but from a web client (same user as the iOS app) ignore the connection request
iOS app should not receive any notifications
