do not error task loading if task was unable to load the answer

[smadbe]

Description

Currently, if a task is unable to load an answer (for instance, wrong format), the task loading fails.

New behavior: it will load the task and let the task explain that the answer was not loaded

Test cases

• [ ] Case 1: BEFORE

  1. Given I am the usual user
  2. When I go to this task which always fails on answer loading
  3. Then I see the platform error for loading

• [ ] Case 2: AFTER

  1. Given I am the usual user
  2. When I go to this task which always fails on answer loading
  3. Then I see the task loads
