sqlite cached_statements workaround

[wjblanke]

Purpose:

Newer versions of python return incorrect sqlite results if cached_statements is nonzero. See:

python/cpython#118172

Current Behavior:

cached_statements is set to default

New Behavior:

cached_statements is set to 0. Chia rarely repeats the same sqlite queries so hopefully this does not affect performance.

Testing Notes:

None

Chia rarely repeats the same sqlite queries

I don't think this is true. Many of our queries are parameterized, and can be pre-compiled. I doubt this would have a noticeable performance impact though.
