The solved time is blank if there are 2 large inputs

```
What steps will reproduce the problem?
1. Participate in a contest with some problem having 2 large (or small) inputs
like Problem C of Qualification Round of 2013
2. Run gcj_get_status.py.
3. The solved time of the second large input is blank.

I tracked the running process, and found that the input_id field of
UserSubmission of large2 in HTTP response is 1. However, 2 is correct.

首先針對 gcj_get_status.py 執行三個重現步驟，並檢查對於大型輸入，UserSubmission.input_id 是如何被讀取的。將 large2 回報的 input_id 與預期值 2 進行比較，接著確認兩個大型輸入都已填入 solved time。
