If an unexpected exception occurs during checking for Journaling table then DbUp re-runs all scripts and potentially destroys lots of data

Hey guys,

I'm trying to raise attention to this issue that i raised. Maybe i'm missing something but this seems pretty critical.

https://github.com/DbUp/DbUp/issues/271

I'm at least looking for confirmation by those who have worked with this before that my analysis is sound. If so, and if i make a pull request with a fix, is there a high probability it will be accepted. 

Thanks
