rdbms: Lazy-init DatabaseDomain::getId()
Follows-up 847b91b.
Noticed that in Xenon profiles, about 25% of Database::__construct

* Database::__construct
* DatabaseDomain::__construct/convertToString/array_map
* DatabaseDomain::newUnspecified
* DatabaseDomain::__construct/convertToString/array_map
* DatabaseMysqlBase::open
* mysqli::*
