Fix incorrect EditDir path in TestAzureContainerRegistry (#880)

Prior to this change, EditPath pointed to a non-existing directory so
this test wasn't testing what's expected.. recent versions of Pulumi
make this error a hard error; also we probably want the test to actually
test the intended state transition encoded in the edit dir, hence this
change.
