Removing dist reference info from Artifact Repository

The getComposerInformation method adds dist information to package. This includes reference, which holds the name of the zip file. For e.g. "MyPackage-1.2.zip". 

Now, when using satis for hosting these packages, it uses the same code for archiving composer packages implemented at https://github.com/composer/composer/blob/master/src/Composer/Package/Archiver/ArchiveManager.php

In the implementation, getPackageFilename() adds the distReference info to the file name, which makes the zip file created at the end to be weird. Like "jay-logger-1.2-MyPackage-1.2.zip.tar". I am not sure if there is any other use of dist reference in Artifact Repository, but this would stop causing that issue.
