Delete package assets

[vs-dsva]

In case of Java SNAPSHOT dependencies the assets (pom, jar, md5) are still present after the package deletion. The SNAPSHOT is transformed on the actual timestamp so the assets will just accumulate under the same package version.

EG: Below are two builds one at 19:22:52 and one at 19:52:54. The artifacts share the same DEVELOP-SNAPSHOT version.
