Remove Blob nullptr checks from Volume code

Browse Source 
There's no point in creating a volume without a blob,
since essentially all the functionality of a volume
requires a blob to be used.

Also, VolumeCreator doesn't support creating volumes
without blobs (it can't even figure out the volume type
unless it gets a blob), so it's currently impossible
for a volume to be created without a blob.
