Empty node name when using illegal characters

Steps to reproduce

1.  Use the nodes endpoint to create a node name <test>

   curl http://localhost:8080/magnoliaAuthor/.rest/nodes/v1/website/travel \
   -H "Content-Type: application/json" \
   -X PUT -i \
   --user superuser:superuser \
   --data \
   '{
     "name": "<test>",
     "type": "mgnl:page",
     "path": "/travel/<test>",
     "properties": [
       {
         "name": "title",
         "type": "String",
         "multiple": false,
         "values": [
           "Hello REST"
         ]
       },
       {
         "name": "mgnl:template",
         "type": "String",
         "multiple": false,
         "values": [
           "travel-demo:pages/standard"
         ]
       }
      ]
   }'

Expected results

Either node with name <test> is created/illegal chars are replaced or an error is thrown informing about the wrong name

Actual results

A node with empty name is created

Development notes

info.magnolia.rest.service.node.v1.NodeEndpoint.createNode(String, String, RepositoryNode) could check and validate the passed name and let the user know if the name is not valid.
