Fix missing log entries in web about ems-esp32

[proddy]

There was a bug in the React code, which I fixed in the 3.7.0-dev.1, where the EventStream could be initiated more than once when the web page is mounted, which could account for some messages getting lost. I'll see if this helps with this issue by slowing down the WiFi on a real ESP32 next,.

WebLogService.h had REFRESH_SYNC as 50, I changed to 30 and it may have caused #1611 missing logs, then it was changed to 80. I'll change it back to 30 and see if the fix in the web solves the sync issue.

If you compile with -DEMSESP_PINGTEST it will send a log message every 1/2 second, which i used for testing.

in 3.7.0-dev.2

Wow, no missing logs with 30ms on my old notebook with compiler running in background. I think you can close the issue. Also no doubletts when removing the id checks.

Great, I close this one then. Was a silly thing in how React renders the DOM on page rendering. Before it was easier with onMount().

I've also tested with wait-delay completly removed and buffer 100. Works good. Next i send all buffer messages at once (in one loop), works also, but maybe this blocks the main loop too long and it takes much memory for TCP buffering. Better leave it by one message per loop.
