display: Only use display channel with id 0

Browse Source 
spice-html5 does not support multiple display channels, and will only
use the first one offered by spice-server, and ignore the others. This
can cause issues when using a VM with a configured but unused
org.spice-space.stream.0 spice port as this will create a 'fake' display
channel which is offered by spice-server before the usual qxl display
channel.
This commit favours the display channel with id 0 rather than picking
the first one.
