fix: correctly handle local files with colons (:) in name

[lobis]

Fixes #1447

Looks like fsspec.generic.py:_resolve_fs should not pass a list to split_protocol

@martindurant looks like the CI is failing due to https://github.com/fsspec/filesystem_spec/blob/master/fsspec/core.py#L516 being called with a list argument. This method should only take strings, so I guess this exposed another issue. Being called with a list was previously bypassing the if "://" in urlpath comparison as it's not comparing with the string contents of the list but with the list itself.

Apparently windows does not support : in paths (makes sense I guess). I'll skip the test for windows.

I'll double check in our end that this fixes things and I'll mark this PR as ready.

Update: Looks good!

[martindurant]

It being Thursday evening, a release this week is unlikely.

Could a release come before Dec 13th? That is what matters for decision making.

[martindurant]

before Dec 13th

Yes, I guarantee it. Ping me on Monday if I haven't done it yet.

@martindurant ping!
