Delete tasks

Deletes an explicit selection of tasks. Nothing restores a deleted task once it is pruned two weeks later. Body parameters: - `tasks` (integer array, required): exact task ids, 1 to 50. Answers **204** with no body. - **404**: any id the token cannot reach (another organization, or outside the member's websites) refuses the whole call and nothing is deleted. - **422**: `tasks` missing, empty, over 50 ids, or containing an id that resolves to no row. - **403**: a read-only token.
