Python: Only produce one alert per vulnerable XML sink
...
This made it much easier to debug the current alerts on tests at least.
Notice that it's important that we have `strictconcat` and not just
`concat`, since `concat` will also allow flow to sinks that are not
vulnerable to any kind of XML vulnerability :|

Python: Rewrite sax XML tests
...
The tests for type-trackers were not that interesting, since they did
not have XML input in both cases, which is the problem we were trying
hard to solve.
I did keep the test-case of not-user-supplied url alive as well though
👍
I added OK/NOT OK annotations.
Notice that we report all 4 kinds of vulnerabilities on line 93

best condition to resolve calls. Although this specific change did not
change much, it should help set us up for success in the future 👍

Since that apparently impacts call graph resolution with points-to :O
Also interesting that global flow was only not working for those cases
because of the tricky ifs... still need to 100% figure out how those ifs
are messing up the analysis :|
