Attempting to eat our own dogfood with fntest

Two namespaces, tx.core and tx.korma, have yet to be ported due to
some strange errors that I probably will need help figuring out.
Missed this version bump
Broken test
Ignorance
Uncomment h2 tests only, just to see hang due to "pop without push"
Restore tests after ThreadLocal fix and remove some old debug
Pin the fntest dep
