Exclusion list filter with empty Address Array ignores messages

[Eklow02]

Describe the bug The DefaultNoOperationMessageState does not process the messages correctly, if the proxy filter EXCLUSION_LIST_FILTER is set with an empty addresses range.

To Reproduce Steps to reproduce the behavior:

1. Set the Filtertype to EXCLUSION_LIST_FILTER, but don't add any addresses to the array yet.
2. The method isReceivedViaProxyFilter returns true

Expected behavior If there are no matching addresses the isReceivedViaProxyFilter method should return false.

Platform details:

• Library Version 3.1.6

Possible fix:

private boolean isReceivedViaProxyFilter(@NonNull final Message message) {
        final ProxyFilter filter = mInternalTransportCallbacks.getProxyFilter();
        if (filter != null && !filter.getAddresses().isEmpty()) {
            if (filter.getFilterType().getType() == ProxyFilterType.INCLUSION_LIST_FILTER) {
                return filterAddressMatches(filter, message.getDst());
            } else {
                return !filterAddressMatches(filter, message.getDst());
            }
        }
        return false;
    }
