test: improve path tests

Replaced deepStrictEqual with strictEqual when asserting that the
path is equal to the win32 or posix equivalent, since it is a more
strict check than deepStrictCheck. Also removed third argument
in the check so that if there is an assertion error the properties
that are different will be displayed.
