fix: Filter returned entity result by view columns

[juliusknorr]

When updating rows in a view I noticed a but where the second update operation of the same row wold fail in the frontend.

It turned out that the first update would actually return a column that was not in the view itself which it tried to update then on the next attempt.

This PR introduces filtering for the actual columns of a view in places where we return its data (update/delete).

Steps to reproduce:

• Create a table with some entries
• Create a view that hides one table column
• Open the view and edit a row twice
