Panic with `open folder\` on Windows

[T-Diedrich]

micro panics on Windows when trying to open a folder from a command, e.g. open folder\.

The resulting backtrace is

Micro encountered an error: runtime.boundsError runtime error: index out of range [0] with length 0

This happens whether the folder exists or not and is especially annoying because it is suggested by the autocompletion feature.

On Linux, for open folder/, an error Error: folder/ is a directory and cannot be opened is shown, or Error parsing args Unterminated backslash-escape for open folder\, both of which would be preferable.

The bug is not fixed but I think it is the same with the bug reported in this issue: #2666
