This PR normalises the tenant part of the URL. For example, the following URL https://jitsi-meet.example.com/something@example.com/something@example.com is converted to https://jitsi-meet.example.com/somethingexample.com/somethingexample.com whereas before it was converted to https://jitsi-meet.example.com/something@example.com/somethingexample.com i.e. the tenant part was not normalised
