Autocompletion of s3 paths not working on fish at all

[Kakadus]

Expected behavior

After having mc --autocompletion installed, completing remote s3 paths should be autocompleted.

I know there already exist #3727, but I think this is a different error. If it is really https://github.com/posener/complete, then you should issue a warning when installing autocompletion on fish (because they are broken)

Actual behavior

Only local paths are completed by fish

Steps to reproduce the behavior

1. install autocompletion mc --autocompletion
2. mc ls myminio/ + TAB

mc --version

It is only tested on bash or zsh. Fish is not expected to work or neither we have the bandwidth to address it.

Feel free to send a fix if you can.

Note that https://github.com/urfave/cli/ (whose (a bit outdated) fork https://github.com/minio/cli) supports fish completions since urfave/cli#848. Maybe updating mino/cli will help?
