Refactor Layer Filter Catch

[allywarner]

In LayerFilter.cc line 939, there is a try catch that doesn't throw an exception so they will be skipped undetected. This is high-level code and will take some work to find proper exceptions for different layers.

This was a problem again. @jessdtate should at least some error or log message come through instead of doing nothing and then reporting success?

log/error would work be fine for now
