Search fixed.

If anime series total is more than 9, and next series is less then 10,
next series string representation is prefixed with 0.

For example.

"Aku no Hana 4" is searched as "Aku no Hana 04" because total series is 13.

But

"Kizuibito 3" is searched as "Kizuibito 3" not "Kizuibito 03" because total series is 5.
