Commit 9d7306001 introduced a syntax error by including a line break in the
description.

this package doesnt play well with demandimport
it hast to be importet at start

A SignedPreKey should only be generated once at install time
A SignedPreKey rotation can be implemented at a later point.
To generate a new SignedPreKey for every publish is overkill
and there is missing a deletion mechansim for old, not used,
SignedPreKeys, which is a potential security risk.
