This is very much like the Ruby query, except we also have the origin
that does the disabling.

4861a980be Python: Fix cryptography modeling 
The old code was my own suggestion, that I thought would just work, but
was also slightly skeptical about.

I tested out whether it works with the code below

```codeql
predicate foo(int input, string res) {
  input = 1 and res = "that was one"
}

from int input, string res
where
  input in [1, 2] and
  if foo(input, res)
  then any()
  else res = "not one"
select input, res
```

which gave the 3 results

```
1 |	that was one
1 |	not one
2 |	not one
```

only by rewriting the code to be the one below, did I get down to the 2
results I actually wanted. So I've done the same kind of rewrite in the
commit.

```codeql
predicate foo(int input, string res) {
  input = 1 and res = "that was one"
}

from int input, string res
where
  input in [1, 2] and
  if foo(input, _)
  then foo(input, res)
  else res = "not one"
select input, res
```

a8b4b6a374 Python: Move test-modeling to API-graphs 
Notice that although we loose the contrived examples in `test.py`, we do
gain support for real-world test-case construction, which seems worth
the tradeoff.
