PyPiHostedFacet does not delete TempBlob on getIndex

In PyPiHostedFacetImpl on getIndex() createIndexAsset() is called which creates a TempBlob that is never cleaned up.

I believe the TempBlob created should be wrapped in a try block like the others so this TempBlob is deleted after getIndex

 

```

private Asset createIndexAsset(final String name,
final StorageTx tx,
final String indexPath,
final Bucket bucket) throws IOException

{ .... TempBlob tempBlob = storageFacet.createTempBlob(new ByteArrayInputStream(html.getBytes(UTF_8)), HASH_ALGORITHMS); ... }

```

 

Should be 

```

try (TempBlob tempBlob = storageFacet.createTempBlob(new ByteArrayInputStream(html.getBytes(UTF_8)), HASH_ALGORITHMS);
```
