Nick Craig-Wood 0fa68bda02 fspath: fix path parsing on Windows - fixes #5143 
In this commit

8a46dd1b57 fspath: Implement a connection string parser #4996

The parsing code was re-written. This didn't quite work as before,
failing to adjust local paths on Windows when it should.

This patch fixes the problem and implements tests for it.
