patches/ExternalMethod update patch for Zope4

In the changes from ExternalMethod 2.13.1 -> 4.5, now ExternalMethod
define __code__ (and __defaults__) to a computed attribute calling
getFunction, but getFunction is different in our patched class, so
when unwrapMethod tries to get __code__, it will raise and mapply
will not consider the external method as being callable, so a simple
__repr__ of the ExternalMethod will be used as response body when
published.

By defining __code__ to something using our patched logic, this
problem does not happen.

There's also a TODO because DevelopmentMode is now True, which uses
a different code path which was causing TypeError, because getPath
returns None, which os.stat does not accept.
