Filter subscribe on 2 different nwaku nodes doesn't work reliable

[fbarbu15]

This is a bug report

Problem

• Have a js-waku ligh node and 2 nwaku nodes.
• From js-waku create 2 filter subscription objects, one for each nwaku node.
• Send messages for both subscriptions.

50% of the time the message send for the 2nd subscription is lost

I tested this by having the DefaultPubSubTopic on both nwaku nodes but also having different pubSubTopics (in the context of static sharding) and the issue reproduces in both cases.

I have a test that reproduces the issue here. Test fails 50% of the time at expect(await messageCollector.waitForMessages(2)).to.eq(true); because only the 1st message is detected. In order to reproduce this you need to disable the mocha retry mechanism from .mocharc
