fix dynamic assignment of address parts

fix dynamic assignment of address parts

A boolean check for dynamic changes of address parts is not
sufficient. The order of choice should be:

 1. an addr:* part matches the name
 2. the address part surrounds the object
 3. the address part was declared as isaddress

The implementation uses a slightly different ordering
to avoid geometry checks unless strictly necessary (isaddress
is false and no matching address).

See #2446.
