I started by removing all .\\ from the shlfileop.c test file in msvc
and the tests all passed , but three of the tests failed in wine.
This patch removes the redundant .\\ and fixes a bug when files in the
file list aren't a part of a directory (.\\).
* Remove redundant .\\ from the shlfileop tests.
* Fix a bug where a file being deleted has to be listed with a directory.
