Title: Errors are cleared when a model is loaded

### Issue

When loading a model in Batman, any validation errors that were added to the model remain. There is no need to keep the errors because on load the model is reset back to it's persisted state.

### Fix

Clear the errors on the model when it is successfully loaded.
