This pull request makes all columns of the task list sortable. It works similar to pull request #5360.

In order to keep the elastic search index up-to-date, re-indexing of tasks is required when:

• a new correction comment is added or resolved (due to the column showing the correction comment status)
• the process is saved, e.g. its title changes (due to the process title column)

Did a code review but I did not have enough time to test functionalities within the application.

Tested and works very well!
