RepositoryRestMvcConfiguration should use defaultMessageConverters in extendHandlerExceptionResolvers

[rajp33]

Right now the RepositoryRestMvcConfiguration uses the defaultMessageConverters property :

spring-data-rest/spring-data-rest-webmvc/src/main/java/org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.java

Line 776 in 56c271d

er.setMessageConverters(defaultMessageConverters.get());

which is lazily loaded to all beans matching type HttpMessageConverter

spring-data-rest/spring-data-rest-webmvc/src/main/java/org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.java

Line 291 in 56c271d

this.defaultMessageConverters = beansOfType(context, HttpMessageConverter.class);

However there is also a bean defined:

spring-data-rest/spring-data-rest-webmvc/src/main/java/org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.java

Line 798 in 56c271d

public List<HttpMessageConverter<?>> defaultMessageConverters(

that I think should be used instead. The property isn't necessary and circumvents application wide customization of the message converters present in the bean:

spring-data-rest/spring-data-rest-webmvc/src/main/java/org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.java

Line 828 in 56c271d

configurerDelegate.get().configureHttpMessageConverters(messageConverters);

Should be a very small PR, happy to submit if needed :)
