patch_inplace() had no unit test at all. Add a happy-path case mirroring an existing patch() example, and -- more importantly -- pin its distinguishing contract versus patch(): when a multi-operation JSON Patch fails partway through, patch_inplace() (which mutates the document directly, operation by operation) leaves whatever operations already succeeded applied, whereas patch() (which applies the patch to an internal copy that is discarded on exception) leaves the original completely untouched either way. Verified empirically against the current implementation before writing the assertions. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
