Bug: Try to remove TvShow twice in RECENTLY_AIRED

If a `ParseException` is thrown the current shown already gets removed from `mTvShowList`. The old if-statement try to remove the show again, while `i` is already decremented in the catch-clause. This will result in an `ArrayIndexOutOfBoundsException`:

```
Caused by: java.lang.ArrayIndexOutOfBoundsException: length=63; index=-1
            at java.util.ArrayList.remove(ArrayList.java:405)
            at com.miz.loader.TvShowLoader$TvShowLoaderAsyncTask.doInBackground(TvShowLoader.java:336)
```
