[CXF-6163] Fixed xsd:any behaviour when used with minOccurs=0, maxOccurs>1

* xsd:any deserializer does not go into infinite loop when xsd:any cannot match any element and minOccurs=0

Here is how generated code now looks like:
```javascript
    var anyObject = [];
    var matcher = new org_apache_cxf_any_ns_matcher(org_apache_cxf_any_ns_matcher.ANY, 'urn:...', [], null);
    var anyNeeded = 0;
    var anyAllowed = 9223372036854775807;
    while (anyNeeded > 0 || anyAllowed > 0) {
     var anyURI;
     var anyLocalPart;
     var anyMatched = false;
     if (curElement) {
      anyURI = cxfjsutils.getElementNamespaceURI(curElement);
      anyLocalPart = cxfjsutils.getNodeLocalName(curElement);
      var anyQName = '{' + anyURI + '}' + anyLocalPart;
      cxfjsutils.trace('any match: ' + anyQName);
      anyMatched = matcher.match(anyURI, anyLocalPart)
      cxfjsutils.trace(' --> ' + anyMatched);
     }
     if (anyMatched) {
      anyDeserializer = cxfjsutils.interfaceObject.globalElementDeserializers[anyQName];
      cxfjsutils.trace(' deserializer: ' + anyDeserializer);
      if (anyDeserializer) {
       var anyValue = anyDeserializer(cxfjsutils, curElement);
      } else {
       var anyValue = curElement.nodeValue;
      }
      anyObject.push(anyValue);
      anyNeeded--;
      anyAllowed--;
      curElement = cxfjsutils.getNextElementSibling(curElement);
     } else {
      if (anyNeeded > 0) {
       throw 'not enough ws:any elements';
      } else {
       break;
      }
     }
    }
    var anyHolder = new org_apache_cxf_any_holder(anyURI, anyLocalPart, anyValue);
    newobject.setAny(anyHolder);
```
* xsd:any serializer does not throw an exception when xsd:any element is being passed as empty array and minOccurs=0
