Improve error handling and robustness

This catches an error that seems to occur when switching from one app to another before the first app has loaded which otherwise prevents loading the second one.

This avoids calling blobs.want if a blob is already present locally, since otherwise blobs.want may broadcast the want to peers.

This uses a blobs.size call to check for the presence of a blob, since historically blobs.has could sometimes trigger wanting a blob.

It also adds use of async/await.
