Failing to list subfolders when server has an IPv6 address

[althonos]

Hi there!

I'm running Kodi Leia v18.9 on Arch Linux, with v1.0.6 of this addon. I have not confirmed if this bug affects Matrix as well, but I'm dowloading it now to try.

Description

I've noticed a bug when using an IPv6 SSH server: I am able to connect to the server from Kodi and to list the root path that I configured in the source configuration, but I cannot enter any subfolder.

After checking the log, it seems that the square brackets around the IPv6 host are discarded, leading to an invalid URL being built to explore the subfolders. Here's an extract of the logs (with phony IPs in lieu of my own ones):
