'Resume' needs to apply missed logs

[jwallet]

needs : MR #88

using pause/resume, if we resume, all missed logs are ignored. we changed that so if we resume, the logger will get updated with all missed logs.

maybe it will be better to have:

• watch/unwatch (record/stop) (e.g.: record in browser network tab)
• freeze/unfreeze (pause/resume)

changes:

• changed the example to send random requests (easier to see which ones were part of pausedRequests)
• keep an array of requests while the logger is paused and apply all missed logs to the queue when resumed
