Subject: [PATCH] Type Task.perform as a property

perform is bound at runtime (this.perform = this._perform.bind(this)),
but typed as a method, so typescript-eslint's unbound-method reports
{{on "click" this.task.perform}}.

As a property, its args are checked contravariantly: a Task<T, [string]>
no longer fits Task<unknown, unknown[]>. Task<any, any[]> still fits.
