object-cache: Avoid use after free of task error

The error should not be touched after passing it to
`g_task_return_error()` as noted by its documentation:

  Note that since the task takes ownership of @error, and since the
  task may be completed before returning from g_task_return_error(),
  you cannot assume that @error is still valid after calling this.

However, previously, the code did try to free error since the
`local_error` was defined with `g_autoptr(GError)`.
