Fixed UpdateBuilder.update() / DeleteBuilder.delete() always return 0 when WAL enabled

Fixed UpdateBuilder.update() / DeleteBuilder.delete() always return 0 when WAL enabled

1. The root cause is the same as referred in Fixed update always return 0 when sqlite WAL enabled #131
2. Maybe reflection is necessary, execSQL returns void, but executeSql returns correct value
3. Calling methods in a compatible way has been verified and correctness is guaranteed, if executeSql failed, call execSQL
