This adds a random suffix to test table names so that it's possible to run the same test more than once in a second without getting name collisions. I chose a random number here because it's simpler, but I could imagine other solutions like an incrementing counter also working with a bit of additional complexity.

This adds `plugin.ValidateNoEmptyColumns` which will handle all of the empty Column verification. This should be used in nearly every single plugin. 

In the future if we add more validation we can add more validation functions  and have a single wrapper around them like `plugin.ValidateSync()`
