Handle it only if self.deferred wasnt called yet, otherwise that's just
an out-of-sync call from a scheduled deferred. Since it was already
logged, it's ok to ignore.

After refactor, the client secret bootstrap logic was flawed, and remote
secret was not being saved properly. This commit fixed that and tries to
improve the bootstrap code to make it more clear.

In order to be able to change passphrase, token and offline status of
soledad from the bitmask client api, the secrets api also has to be able
to use up-to-date values when encrypting/decrypting secrets and
uploading/downloading them to the server. This commit makes public some
soledad attributes that were previously "private" (i.e. used to start
with "_" and were not meant to be accessed from outside), and passes the
whole soledad object to the client secrets api. This makes the code
cleaner and also allows for always getting newest values of soledad
attributes.
