An error occurred uncompressing NVD payload

### Current Behavior:

Using the executable WAR. When I run:

`java -Xmx12G -jar dependency-track-embedded.war -port 8081`

as shown in the examples in https://docs.dependencytrack.org/getting-started/deploy-exewar/, for each (from 2002 to 2020) of the nvdcve json files, I get this error in the dependency-track.log for each file:

```

```

### Steps to Reproduce:

When the log file says, "java.nio.file.NoSuchFileException: /home/dilla/.dependency-track/nist/nvdcve-1.1-2002.json", that's because there is no user "dilla" on the host.

There is a user "dogzilla" however. That's the user running the java -jar command.

So if I create a directory mkdir -p /home/dilla/.dependency-track/nist and re-run the java -jar command it works! If delete the /home/dilla/.dependency-track/nist, then it fails with the errors previously posted in this report.

It looks like the code is truncating the "ogz" in dogzilla to make a non-existent user "dilla".

### Additional Details:

(e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

See above. For some reason the code in the WAR is trying to write to /home/dilla. There's no such user on my host. The account I'm using is /home/dogzilla.
