bitbake: toaster: fixes for null values from events

Some of the data values may come of as None through the event system,
and the UI would encounter a problem saving the Configuration.
It would be trying to save these values as NULL in the
database, which is not allowed.

This patch adds more verification for data coming through
the event system.

Other minor updates:
* update for the event model from toaster.bbclass
* minor code flow fix in the event system
