It is wrong to use dir.GetName()+"/" to obtain a slash-terminated directory
name as this results in (usually harmless but at best ugly) double slashes at
at the beginning of the string for the root directory. Add GetNameWithSep() to
obtain the correct result in all cases.

"C:" drive doesn't need to exist under Windows, rely on HOMEDRIVE environment
variable defined in all recent Windows versions to get a valid drive letter
(still fall back to "C:" if the variable is not defined -- we could have use
wxFSVolume to find it then but this seems like an overkill).

fix test cases /usr//bin and /usr///bin: they succeed because wxDir::Exists does not care about redundant path separator (and this holds also for non-Unix platforms);
add some more test case
