Recognize .nessus file names (DefectDojo#4397)

pburkholder · web-flow · commit 7e9e984adfbc · 2021-04-30T10:37:31.000+02:00
As a new DefectDojo user, I was thought I had a corrupt .nessus file, until I renamed it with .xml. This change recognizes XML exports with the `.nessus` extension, matching the documentation at line DefectDojo#245. Also clarifies the error when trying to import a Nessus file.
