Fix inaccurate or missing statements about unflatten (third round-trip failure, empty token, typo), value (type_error.306 before pointer lookup), contains (pointer overload), parent_pointer and operator<< (bad_alloc), out_of_range.410 example, template parameter requirements (resize(n)), and document the URI fragment form and non-unique member names of RFC 6901. Add tests for the unflatten and value() cases. Signed-off-by: Niels Lohmann <mail@nlohmann.me>

nlohmann::json_pointer::parent_pointer
json_pointer parent_pointer() const;
Returns the parent of this JSON pointer.
Return value
Parent of this JSON pointer; in case this JSON pointer is the root, the root itself is returned.
Exception safety
Strong exception safety: if an exception occurs, the original value stays intact. The function is not #!cpp noexcept
and allocates a new JSON pointer, so it can throw #!cpp std::bad_alloc; it throws no library exceptions.
Complexity
Linear in the length of the JSON pointer.
Examples
??? example
The example shows the result of `parent_pointer` for different JSON Pointers.
```cpp
--8<-- "examples/json_pointer__parent_pointer.cpp"
```
Output:
```json
--8<-- "examples/json_pointer__parent_pointer.output"
```
