Needed to be able to return a promise from a test case.

Get rid of the experimental flag for simulcast support, update js-utils for detecting Edge on Android

Switch to using ontrack for remote tracks, re-use mids/transceivers when remote sources are removed and added.

         at P.Connection._dataRecv (strophe.umd.js:3140)
         at I.Bosh._onRequestStateChange (strophe.umd.js:5012)

Update strophejs-plugin-stream-management to fix the crash for
the stacktrace above. It happens only with BOSH.

...connection dropped with an error.

Updates logger to 5ec9235757 in order to support log timestamps.

Build as follows to build (production) bundle size stats:

npx webpack -p --progress --analyze-bundle

Then open the report:

npx webpack-bundle-analyzer stats.json

* Removes Edge support.

* Removes unused dependency.

It should be provided by the environment, just like on web. This avoids bundling
callstats on web, where it won't be used (we dynamically download it).

This reduces the bundle size from about 1MB to 675KB, almost 40%.

js-utils has some, so we need the preset or webpack fails with a syntax error.

* feat: Read the server region from Jingle and broadcast it with statistics.

* feat: Adds the bridge count to local "statistics", refactors conference-properties.

* fix: Emits the conference properties with the event, small fixes.

* ref: Orders the imports alphabetically.

As described by @virtuacoplenny:
[T]he ordering is based on import path, not import name, with different
file depths being grouped together, node modules being grouped together
at the top.

* fix: Keeps JitsiConference#properties always defined.

* fix: Does not fire an event when the argument is undefined.

Could not update karma-webpack to latest as it was not running because of an error:
The "path" argument must be of type string. Received type object
https://github.com/webpack-contrib/karma-webpack/issues/350

* refactor packet2JSON to not use jquery

also added unit tests for it and switched to use chrome-headless instead
of phantomjs

* update package-lock

* squash: undo sha512 to sha1 conversion in package-lock

Solves a GitHub warning about a vulnerability in a
uglifyjs-webpack-plugin dependency.
