John Snow c256263f3d qapi/parser: Fix token membership tests when token can be None ...

When the token can be None (EOF), we can't use 'x in "abc"' style
membership tests to group types of tokens together, because 'None in
"abc"' is a TypeError.

Easy enough to fix. (Use a tuple: It's neither a static typing error nor
a runtime error to check for None in Tuple[str, ...])

Add tests to prevent a regression. (Note: they cannot be added prior to
this fix, as the unhandled stack trace will not match test output in the
CI system.)
