Historic IP addresses included in invites are rendered invalid by omitting the last digit of the port #136
Description
Using the new certificate format, IP addresses included in an invite are rendered invalid by omitting the last digit of the port.
Reproduce
Create an invite that includes the complete IP address history. Add this friend in another instance or use a Base64 decoder to look into the invite. Observe that the last digit of the port is missing, i.e. 3ipv6://[2103:c7:9720:d377:165d:efb4:d504:d25e]:420 when port "4200" was used.
Workaround
Use the "old certificate format". In this case, ports are properly included
