NuGetDefence.lib: json report file not showing the list fo vulnarable packages

[chiluap]

After scanning the json report file does show the number of affected packages, but the list of issues is empty.

To Reproduce Steps to reproduce the behavior:

1. scan a project with issues configuring json repotfile:

{
 "VulnerabilityReports": {
    "OutputTextReport": false,
    "JsonReportPath": "./TestResults/DependencyErrors.json"
  }
}

2. the repotfile looks like this:

{
  "VulnerabilitiesCount": 11,
  "Packages": []
}

Expected behavior Packages array to not be empty.
