Node.create() which has a compatible signature with Node.__init__()
takes in a single `children` argument rather than relying in unpacking
*args in Q.__init__() which calls Node.__init__().
In addition, we were often needing to unpack iterables into *args and
can instead pass a list direct to Node.create().
- Removed use of Q.deconstruct() in Q._combine().
- Simplified and optimized Q.__invert__() by taking a shallow copy and
swapping the negated attribute only.
- Simplified construction in Q._combine().
- Simplified conditions in Q._combine() as Q.conditional = True the
first isinstance() check is unnecessary.
- Removed copy.copy() branch in Q._combine().

This allows the copy.copy() usage in the Q._combine() method to finish
sooner, instead of having to fallback to using the __reduce_ex__(4)
method.
Thia also avoids having to fall into copy.copy() at in Q._combine(),
when combining a Q() with another Q().

Node._new_instance() was added in
6dd2b5468f to work around Q.__init__()
having an incompatible signature with Node.__init__().
It was intended as a hook that could be overridden if subclasses needed
to change the behaviour of instantiation of their specialised form of
Node. In practice this doesn't ever seem to have been used for this
purpose and there are very few calls to Node._new_instance() with other
code, e.g. Node.__deepcopy__() calling Node and overriding __class__ as
required.
Rename this to Node.create() to make it a more "official" piece of
private API that we can use to simplify a lot of other areas internally.
The docstring and nearby comment have been reworded to read more
clearly.
The tests for creating new instances or copying instances of Node and
its subclasses didn't fully capture the behaviour of the implementation,
particularly around whether the `children` list or is contents were the
same as the source.
Node.subtree_parents was removed in
d3f00bd570. That commit also added
Q.clone() which was identical to WhereNode.clone(), but lacked the
docstring. Q.clone() was later removed in
b454e2cbc9.

- Using the |yesno filter.
- Using the |unordered_list filter.
- Unnesting {% if %} where not required.
- Not duplicating {% if %}.
