That's a good question, thanks for pointing this out.
The good news is that the filter is sent using SendStr which ignores empty
strings:

PluginInstance::SendStr(uint32_t id, std::string str)
{
    if (str.empty())
        return;

so we'll rely on spice-gtk defaults when the string is empty.
Next question -- which is not really a problem for now since the various
properties are only sent once after the client has started -- is how do we
unset a previously set filter using the controller. I don't think there's
any way to do that currently, but it might be interesting to do at some
point..
