Fix non-ASCII letter in Statistics.sendActiveDeviceListEvent() method

Call addNewFabric only if callstats is initialized, there are certain situations when the init callback for some reason is slow and we call addNewFabric before callstats is initialized and we skip the peerconnection reported so we are missing the stats. Reports data only if callstats had initialized, adds caching of associateMstWithUserID calls.

You can call static Statistics methods which will internally handle callstats instances to send stats. Drops handlers and JitsiMeetJS references.

Logs versions of components and library version. Logs shard and region if available.
