Clear cache might be a bit too aggressive

I just added a new subject and session, added the measurements and thought I'd try and select the session I just created, but this gave the following error:

Traceback (most recent call last):
  File "C:\Dropbox\Development\Pawlabeling\pawlabeling\widgets\database\sessionwidget.py", line 94, in put_session
    pub.sendMessage("put_session", session=session)
  File "C:\Anaconda\lib\site-packages\pubsub\core\kwargs\publisher.py", line 30, in sendMessage
    topicObj.publish(**kwargs)

    self.__sendMessage(data, self, iterState)

    self.session_id = session["session_id"]
KeyError: 'session_id'

So it seems its deleting things it shouldn't be deleting.

Turning off clear_cached_values solves the problem. While I thought only model.py was affected, I forgot clear_cached_values publishes the same call to the whole app, so things are deleted everywhere. I guess I'll have to rethink what can/should be cleared when.

I've moved it to put_subject, a far safer choice!
