Bug in upstream Nexus Script prevents assigning non-default BlobStore for Nuget repositories

[InfoSec812]

When provisioning Nuget repositories from Kubernetes ConfigMaps the BlobStore argument appears to be malfunctioning. The implementation HERE indicates that this should be a supported capability, but JUST for Nuget repositories it is not working. All other repository types seem to be provisioned correctly.

I have started a thread on the Nexus mailing list to see if we can find the root cause of this error as the Unit Tests in this project show that the methods are being called correctly but the expected result is not achieved.

This was a mistake on my part in the plugin code. The issue was that byu default Nexus already had the repositories I was trying to create and the plugin quietly refused to modify an existing repository in order to prevent loss of data. I will be adding a log message to the filter predicate to announce when this happens in the future.
