I've only lightly tested this patch, but I think it should resolve the 
issue. It only sets the "home-directory" connection property when a 
connection is already established. Otherwise, it just uses the cached 
value (if any).

Maybe there's a cleaner way to do this though; opportunistically setting 
a connection property like this seems like something there might be a 
special function for in Tramp, but I didn't see one after a bit of 
looking so this is what I went with.
