Some additional tests for Model.__eq__()

Following up on this note from Danny: "Model._equivalent doesn't have
checks that properties are the same (only can happen for an Expando) and
a check for property names with a . (only can happy with a
StructuredProperty) (added in #6695)"

After looking at this, while the original Legacy code had code
specifically to deal with these cases, it doesn't appear to be
necessary. Tests for equality work fine even without explicit code for
Expando and StructuredProperty. Added tests prove this is the case.
