[Vmware][Deploy-as-is] DB exception when the template/appliance has empty default values

[nvazquez]

Cannot deploy VM from a template when:

• 'Read Settings from OVA' = true
• The template has one or more properties without a default value (null values)

Example (missing the ovf:value property):

<Property ovf:key="SCHProxyPort" ovf:type="string" ovf:userConfigurable="true">
        <Label>Smart Call Home HTTP Proxy port number</Label>
        <Description>HTTP proxy server port number (Defaults to port 80 if omitted.)</Description>
</Property>
