fix: invite same email to the multiple teams

This should fix the invites bug when you have incorrect behavior if you invite the same email to different teams.

Problem:

Logic is so that if a user sends an email that is already in the invite list we should just update the existing one instead of creating a new one with the same email.
The issue was the condition that filters existing emails. The condition didn't check the teamId and as a result, if you already have an invite to team A, when you try to create an invite to team B, an invite to team A will be selected as an "invite to update", but not as an "invite to create".

PR also fixes incorrect team names in the invite email
