fix: filter missing messages

[weboko]

Problem

This PR addresses 3 problems:

• When peer is renewed and it was used in filter subscription it is not added into missing messages hash map.
  Because of that this.addHash fails during processing of incoming messages and that terminates callback's invokation.
• Because of bug introduced for keep alive feature - pings are not done properly.
• To be more align with RFC - DEFAULT_MAX_PINGS has to be changed to 2;

Solution

Fix bugs, change const.
