ReadMultiple w/ request_dict bug fix

[alecjohanson]

This may be fixing the

TODO : Need improvement here and look for the property identifier that is coming from the response
            Then we'll be able to support multiple properties for the same object in the read multiple function

This fixes an issue when for example, reading with a request dict like:

binary_iov = {
    'address': "<ip>", 
    'objects': {
        'binaryInput:1': ['objectName', 'presentValue'],
<...>
        'binaryInput:8': ['objectName', 'presentValue'],

        'binaryOutput:1': ['objectName', 'presentValue'],
<...>
        'binaryOutput:8': ['objectName', 'presentValue'],

        'binaryValue:1': ['objectName', 'presentValue'],
        'binaryValue:2': ['objectName', 'presentValue'],
        'binaryValue:3': ['objectName', 'presentValue'],
<...>
        'binaryValue:16': ['objectName', 'presentValue']
    }
}

Then calling: my_controller.properties.network.readMultiple(<ip>, request_dict=binary_iov)

Without this change, the returned value has the form

{
    'binary-input,1': [(<PropertyIdentifier: present-value>, <BinaryPV: inactive>)],
    ...
    'binary-value,16': [(<PropertyIdentifier: present-value>, <BinaryPV: inactive>)],
}

Not including the requested objectName

With this change the returned value has the form:

{
     'binary-input,1': [(<PopertyIndentifier: object-name>, 'BI 1'), (<PropertyIdentifier: present-value>, <BinaryPV: inactive>)],
    ...
     'binary-value,16': [(<PopertyIndentifier: object-name>, 'BV 16'), (<PropertyIdentifier: present-value>, <BinaryPV: inactive>)],
}

Which includes the requested object-name and present-value

I'll have a look. Thanks
