Resolve args.files before changing directory (helix-editor#8676)

* Resolve args.files before changing directory

* Removed the open_cwd work-around now that the path is full

* If -w is specified, use that as the working directory

* Open the remaining files in the argument list, also when the first is a directory

* Use an iterator access the files argument
