add test case that made me add special test for sqlite in insertplayers - can't repeat now so removing test. Error was that a unicode type (name) was encoded to UTF-8 by Charset.to_db_utf8() and then errored when passed to sqlite. sqlite3 can handle unicode types directly so I added a test to skip the to_db_utf8() if using sqlite. Perhaps problem was caused by moving hand history between machines (but shouldn't it still work anyway?)
