DD-593 integration test fixes multi license

[mderuijter]

Running an Integration Test on our dd-dtap env:
source (Getting Set Up to Run REST Assured Tests)

Had a hard time installing the right Maven version on Centos 8 so i forwarded port 8080 to my localhost instead (VirtualBox -> Settings -> Network(advanced) -> Port Forwarding):

# make sure there are no :BlockedApiEndpoints for this to work, I deleted both :BlockedApiEndpoints and :BlockedApiPolicy from the database directly

# mysteriously needed according to docs
curl -X PUT -d 'burrito' http://localhost:8080/api/admin/settings/BuiltinUsers.KEY

curl -s -X POST -H "Content-type:application/json" -d "{\"assignee\": \":authenticated-users\",\"role\": \"fullContributor\"}" "http://localhost:8080/api/dataverses/root/assignments?key=$(apikey)"

# change directory to local dataverse to run test
mvn test -Dtest=AdminIT -Ddataverse.test.baseurl='http://localhost:8080'

# run the full IT suite:
mvn test -Dtest=DataversesIT,DatasetsIT,SwordIT,AdminIT,BuiltinUsersIT,UsersIT,UtilIT,ConfirmEmailIT,FileMetadataIT,FilesIT,SearchIT,InReviewWorkflowIT,HarvestingServerIT,MoveIT,MakeDataCountApiIT,FileTypeDetectionIT,EditDDIIT,ExternalToolsIT,AccessIT,DuplicateFilesIT,DownloadFilesIT,LinkIT,DeleteUsersIT,DeactivateUsersIT,AuxiliaryFilesIT -Ddataverse.test.baseurl='http://localhost:8080'
