Remove shape check from Domain.__eq__ and fix anon-domain copy

* Remove shape check: The shape is already verifies when checking all
dimensions are equal. Because the shape is not always well defined,
this was failing on homogenous non-integer/datetime domains.

* While testing the above change, an error where the filters were not
 being copied when adding all anonymous dimensions to a domain was
 caught and fixed as well.
