sqlite unique primary key generation bug

[Paberu85]

"continue" statement forces loop condition re-evaluation - while(conflict), this "conflict" value is initialized to false and does not change inside of loop body (loop will repeat itself only if condition is true, but condition is hardcoded false and will exit after first iteration) - loop will execute only once even if non unique primary key was generated, which will result in a sqlite crash (unique pk assertion failure)
