A GetVariant that begins before StoreVariant finishes can find the
variant file but not yet its .meta file, and so reads
application/octet-stream. When it adds that to memory after the store
added the real type, the wrong type is served to every later hit. The
part of GetVariant that runs after its check of memory moves, unchanged,
into loadVariantWithMeta, so the test can run it after a store. The
test fails now.
