This check doesn't seem to make sense.  Essentially, "unless" means "not 
if" when testing if the file exists.  The template resource within that 
block should be idempotent without that File.exists check.

It could lead to undesired behavior if you want to update an already 
managed repo.  I cannot say I have noticed this effect in all the time 
I've used this resource, however.  It could be a bug.  Unless I am 
reading that wrong, and the line is intended for some other purpose.
