    report_root should always use context.user

    The RootHistory intends to record by whom and when the root user of the
    underlying datastore backend was enabled. So the "user" column should
    always be set to the context user, not the actual root user in the
    database. But report_root(and report_root_enabled in
    taskmanager.models) use the database user instead, this is not correct,
    This patch will fix.

    Also remove the "user" argument from Root.create() and
    HistoryRoot.create() because the context is already passed in as an
    argument when these methods are called.
