Restore id column in History table

The id attribute is used in the definition of the `update_time`
column_property.

Since id is inherited from a mixin, it is not available on the History class at mapping time.
The `remote_side` and `foreign_keys` parameters of the relationship
function face the same problem; however they can be defined as a
callable, which defers resolving the identifiers they contain, which
solves this problem. `column_property` does not accept a callable in
place of its argument, so the only way around is to define it after the
class has been defined - and we do so for several classes (see bottom of
the model/__init__ module. However, it appears to be impossible to use
this approach for the update_time attribute because it is also the name
of the database table column, which is defined inside the class
definition. Moving that column definition outside the class would add
unnecessary complexity: redefining the id column, I think, is the
reasonable approach here.
