Removing of configuration fails if IPV6 address is not expressed in the shortest form

[Prodec-]

I think this issue is related to the #8.
When I tried to run the script, it always failed in the part where old configuration is removed. I did a little digging and apparently the culprit was that I had the IPV6 address of the interface in the configuration written as xxxx:0000:0000:0000::1/128 instead of the shortest form of xxxx::1/128.
The part where the script queries for the address ( ip -oneline address show dev $INTERFACE.... returns the ip address in the shortest form, so the script doesn't recognize the address stated in the config.

I managed to fix my config by shortening the address to xxxx::1/128, and the script now runs successfully.
Maybe there could be a check for the address format in the script?

Template rewrite #55 will cause this section of the script to be removed soon since it was a workaround to the flawed template.
