pylint #107062 "E1101: %s %r has no %r member" should take a hint from hasattr [open]

In the following code, we take care to check the existence of a dynamic attribute
before accessing it, but still, pylint issues a false positive:

E: 3,38:A.argh: Instance of 'A' has no 'blurb' member

---- 8< ----
class A(object):
def argh(self):
if hasattr(self, "blurb") and self.blurb:
print "yes"
print "no"
