add property to let client indicate proper initialization
In the original context, it was suggested that the soledad.client should expose a simple property to let user know if it has been properly initialized or not (mainly, if shared secrets have been generated AND uploaded to the server). (keymanager probably should do something similar)
this would solve some issues like trying to generate key material again for an already-initialized account.

During the blobs iteration, I thought that we could use a generic initialization document to store the blob initialization.
