depth() don't work correct

[TomFuch]

Describe the bug
When path() is the root of a windows driveletter, depth(0) is not restricted to the root. It will also find files in the first directory level.

To Reproduce
Steps to reproduce the behaviour:
const files = FileHound.create() .path('z:\\') .depth(0) .find();

Expected behaviour
Files are also detected in the first level of subdirectories.
