Partial order stuck at ‘new’ due to no snode selection

[shrnkld]

STR:

1. disconnect from the internet (simulates lost or poor network connection)
2. place a partial order via console using dxmakepartialorder (see https://api.blocknet.co/#dxmakepartialorder)
3. wait until the new order shows status created in console
4. reconnect to the network
5. use dxgetorder with the order ID created in step 2 to verify order status

Error result: XBridge error: order may be stuck, trying to submit order to previous snode

The error keeps looping and never seems to find a snode to submit the order to.

Expected behaviour: the order should be placed once xbridge is reconnected to the network, transitioning from new to created.

To do:

• [x] investigate and debug the function checkAndRelayPendingOrders which seems to be related to the issue
• [x] add more logging if required
