[IMP] mail: add message_log with view helper

This commit allows to log a note and bypass notification process using a
template. The method _message_log_with_view has been added. This method
render the template using the given view and values (in kwargs) to make the
body before calling _message_log().

This process is done by the intermediary method _message_compose_with_view that
is now common to message_post_with_view and _message_log_with_view has it
follows the same template preparation process.
