Update to newer version of Spring Data JPA (1.8.0.RELEASE - 1.9.2.RELEASE)

While trying to integrate with lightadmin, I encountered the following exception at the initialization of the jpaMapppingContext

Caused by: java.lang.NoSuchMethodError: org.springframework.data.jpa.mapping.JpaMetamodelMappingContext.<init>(Ljavax/persistence/metamodel/Metamodel;)V

After having a look I've found the problem comes from light-admin/lightadmin-core/src/main/java/org/lightadmin/core/config/bootstrap/JpaMetamodelMappingContextFactoryBean.java file, at line 53 where the JpaMetamodelMappingContext is being initialized.

JpaMetamodelMappingContext context = new JpaMetamodelMappingContext(metamodel);

Newer versions of spring-data-jpa, changed the constructor from one instance of Metamodel to a Set, so basically in order to use light-admin you have to use an older version (e.g 1.7.0.RELEASE)

public JpaMetamodelMappingContext(Set<Metamodel> models)

This contructor also exist in spring-data-jap-1.7.4 .
So, by using this method, it is compatible from 1.7 to 1.9 .
