Actually execute the tests for the getter/setter/deleter tests on properties.

Also fix the test by having the test classes inherit from object.

Are the getter/setter/deleter attributes supposed to be able to chain?  As of
right now they can't as the property tries to call what the property returns,
which is another property when they are chained.
