Empty group cause build model failed because of wro.xsd

[M3lkior]

Hi,

ignoreEmptyGroup property has no effect because of built model from XML failed if does not have at least one element (js, css or group-ref)

this is due to group xsd definition with minOccurs="1" :

 <xsd:complexType name="Groups">
                <xsd:choice minOccurs="1" maxOccurs="unbounded">
                        <xsd:element name="import" type="xsd:string"/>
                        <xsd:element name="group" type="Group" minOccurs="1"
                                maxOccurs="unbounded" />
                </xsd:choice>
        </xsd:complexType>

My wro4j code :

<group name="app-header-all"></group>

Stacktrace :

Thanks!

It's works with an empty <css> or <js> declaration but it's just a hack ;)
