Handle ConfigurationPropertyKeys of spring.datasource.* being set and differing

[aegershman]

These mappings are only correct if either
spring.datasource.data- or spring.datasource.schema- are set. If they're both set (and don't differ) it would break the application

The new script-based SQL database initialization does not support using separate credentials for schema (DDL) and data (DML) changes. This reduces complexity and aligns its capabilities with Flyway and Liquibase. If you require separate credentials for schema and data initialization, define your own org.springframework.jdbc.datasource.init.DataSourceInitializer beans.
