When switching a recipe with a module present in an assembling machine to one with a allowed_module_categories restriction, the game doesn't check if current modules are valid for the new recipes

sample data.lua code:
data.raw.recipe['iron-stick'].allowed_module_categories = {"speed"}

1. place crafting machine 3 and set the crafting recipe to iron gear wheel
2. insert efficiency module
3. switch recipe to iron stick
4. efficiency module stays in

Thanks for the report. Issue is now fixed for 2.0.6

Thanks. I also found another bug related to the report, it looks like beacons ignore the allowed_module_categories field on both recipes and crafting machines
