Ekster happily created new channels with the same as existing channels. Now the channel name is unique and returns the current uid and name of that channel. It seems this currently isn't specified.

It does improve the scriptability of Ek. I can now follow feeds while creating the channel like this:

ek follow `ek channels Blogs` https://example.com/blog/

The channels call will return the uid of the created channel or the uid of the existing channels when it already exists.
