Prior to this commit, RequestMappingViewResolutionIntegrationTests
invoked the following:
configurer.setTemplateLoaderPath(
"classpath*:org/springframework/web/reactive/view/freemarker/");
However, that configuration is invalid since `classpath*:` is not
supported for a `templateLoaderPath`.
Despite that, the tests still passed since FreeMarkerConfigurer already
registers a new ClassTemplateLoader(FreeMarkerConfigurer.class, ""),
which automatically finds template files in the same package as
FreeMarkerConfigurer (for the "spring.ftl" macro library support) and
coincidentally RequestMappingViewResolutionIntegrationTests as well
(which resides in the same package).
This commit therefore removes the invalid configuration and adds a
comment to explain what's going on.
