Get the blob matching the URI either from the VFS or the filesystem.
If the blob exists in the VFS with the specific version then that is returned.
Otherwise the URI is used to try and locate the blob on the filesystem.
This function may throw if the URI do not exists in the internal DB and it refers to a file that do not exist on the filesystem.
