483bd0e863 Python: Fix shared taint tracking tests
Since there was a .ql file, qltest tried to run a test in
test/experimental/dataflow/taintracking/ which failed since there was no code.

d96ef73033 Python: Handle taint for f-strings
Which we seem to not handle in the current taint tracking :O

f-strings needs to be Python 3 only, so enabled that test setup. I really liked
the idea for having the version specific tests right next to the normal tests,
so you don't have to look in
test/experimental/3/dataflow/i/will/forget/to/look/here.

61f89ca3c3 Python: Add tests for shared taint tracking for strings
I adopted the TestTaint testing setup that I made for the "old" taint tracking
tests. This time around we should figure out if we can use .qlref or similar so
it doesn't end up in multiple copies that are not kept up to date :|

The `repr` predicate could probably be placed somewhere better. For now I just
wanted something that could help me. I considered just expanding the `repr`
predicate in `ql/src/semmle/python/strings.qll`, but since it's currently used
by queries, I didn't want to do anything about it.

Anyway, the output it gives is much more useful than seeing this ;)
