Download Endpoint Returns Checksum Files if Maven Classifier Param is Set

When calling /beta/search/assets or /beta/search/assets/download with both the maven classifier and maven extension parameters, the response returns the checksum files along with the asset specified in the extension.

For example calling:

http://localhost:8081/service/rest/beta/search/assets?repository=maven-releases&version=1.0.1&maven.groupId=org.foo&maven.artifactId=bar.project&maven.extension=jar&maven.classifier=blah

Will result in the jar asset as well as its checksum files being returned. It is expected that only the jar will be returned.

Omitting the classifier parameter results in only the jar being returned as expected.
