Rasa: `rasa train` cannot detect changes on lookup tables

[roniemartinez]

Rasa version: Rasa 1.9.5

Python version: Python 3.7.7

Operating system (windows, osx, ...): OSX

Issue:
When adding entries in the contents of the lookup table which is located on a separate file, as per the new standards, running rasa train will not detect these changes and outputs that you can reuse the existing model, instead. After verifying it through the rasa shell nlu, the added items in the lookup table are not detected.

Temporary solution: Delete your models and retrain using rasa train.

Other information: The lookup tables are not located on the data folder.

Not sure if this is the same or a different issue, but we could not get our lookup tables to work at all with DIET classifier ( entity_recognition: True ). It wasn't until we implemented CRFEntityExtractor that the lookup tables were read during training. This seems like either a bug or, if this is known, maybe this information should be added to the documentation.
