Fix or skip a number of failing test on Windows

Several warnings due to a single backslash + char being
interpreted as a special character. Fixed with use of '\\' or
using raw string.

All test failures due to different path seperator or drive
used in expected test data. Fixed by duplicating tests with
differnt reference data and including condition
skips if on windows systems.
