Before this commit, the commit [1] renames the routes to keep the url
and add the id when the user selects a task id.
However, the redirection is missing for `/my/task/<task_id>` due to
an issue in the routes selected for the redirection.
This commit redirects the `/my/task/<task_id>` to `/my/tasks/<task_id>`
to keep the old route accessible.
