vantage6 may create unencrypted tasks in encrypted collaboration

Impact

There are no checks on whether the input is encrypted if a task is created in an encrypted collaboration. Therefore, a user may accidentally create a task with sensitive input data that will then be stored unencrypted in a database.

Workarounds

This is not an issue with the normal workflow, only if e.g. a user with the python client sets encryption to the wrong value.
