tests/basics/string_compare.py: Add test with string that hashes to 0.

dpgeorge · dpgeorge · commit 1bfc774a0861 · 2018-04-05T01:04:38.000+10:00
The string "Q+?" is special in that it hashes to zero with the djb2
algorithm (among other strings), and a zero hash should be incremented to a
hash of 1.
