login: fix login for saved ipv6 addresses

Since we only string concatenated the host + port, ipv6 addresses were
invalid because their missing [] around the ip. To fix that, use
'Uri's 'toString' method but strip the 'https://' prefix when creating
an Uri object again

This now also allows to enter the 'https://' prefix manually
