Fix link from tasks list to task type

[philippotto]

Similar to #2759, but for links to task types.

Mailable description of changes:

• Fix: Clicking on a task type within the task list page was fixed so that the task type page will actually only show the linked task type.

URL of deployed dev instance (used for testing):

• https://fixtasktypelink.webknossos.xyz

Steps to test:

• click on the task type link within the task list view --> task type page should be loaded and search value should be filled with the task type name
• visit task types page via the navbar (everything should work)
• search for something in the task type page and reload the page --> search query should be persisted

---

• Ready for review
