New issue 3061: set attribute history to None when we do an implicit get() of an unset attribute?

Mike Bayer:

see #3060.  We have a lot of problems here due to the fact that:


```
#!python

x = Obj()
x.foo  # is None, sets it to None, doesn't write any history
inspect(x).attrs.foo.history # shows no history due to the get() above.
```
