fix: remove binding teams references

[tlebon]

fix and avoid an issue with a deprecated endpoint GET /teams

Prepares for the removal of non-binding teams by the BE.

Non-binding teams were the concept that a user may have multiple teams. In this case, they would not be bound to any team. In practice, users only have one team and the /teams endpoint always returns an array of 1 object. The only case this does not work is in the self-user case where they do not have a team.

The feature was not used except in this login case, and it is not necessary so it is being removed.
