fix #517

Hello @AlexPalaz, @valeriocomo this does popup a dialog that says "unknown fields removed: categories", which is misleading. categories is not an unknown field:

Interestingly, if you try and load a file with an invalid category AND a valid one, such as:

categories:
  - no_such_category
  - accounting

it gets autofixed and no dialog is shown.

I think all the "autofixes" are better served shown via the warning pane, so they are uniform and all in the same spot:
