Remove instrument related tasks that are visible on the tab Tasks

[anneschuth]

Description

When an instrument / hulpmiddel is selected, we automatically create tasks for all questions that are configured for the instrument. This was an interesting idea, but it was to rough. The proposal is that we remove all these tasks and also for new algorithms we remove the logic that we automatically create tasks for these instruments specific tasks.

This change doesn't mean we are going to remove to task functionality. In another ticket we will add logica to create tasks for selected measures and instruments. This means that for each instrument, we will create one tasks so progress of the instrument can be tracked in AMT.

Technical Implementation

• Drop database tasks
• Tab 'tasks' does not need to be removed (keep as empty columns).
• Business logic adjusted such that the tasks are not automatically created.
