ARROW-10834: [R] Fix print method for SubTreeFileSystem This PR modifies ``` `$.SubTreeFileSystem` ``` to return `NULL` if the named object is not found in the object. This allows the `print()` method of `ArrowObject` to print `SubTreeFileSystem` objects without error. Closes #9168 from ianmcook/ARROW-10834 Authored-by: Ian Cook <ianmcook@gmail.com> Signed-off-by: Neal Richardson <neal.p.richardson@gmail.com>
