Set breakoutRoomLimit to 16

With defaults of 2 backend and 2 frontend bbb-html5 nodejs processes we can handle more breakouts. @ritzalam confirmed no audio changes are needed

Pulled HTML5 locales on Apr 1, 2021

fix: MEDIA_ERROR when joining room using Firefox

Firefox doesn't create a  device called 'default' and we were trying
to set this when user is joining the room. We don't do this anymore, letting
devices to be changed when there's some user request.

Moved outputDeviceId inputDeviceId information to be managed in bridge
(just like we do with inputDeviceId), we don't store this duplicated
information in audio container anymore.

Fixed the eslint warning in "playAlertSound(url) { ..."

We are safe to let users try to change input/output devices because the
device list is retrieved from enumerateDevices.

Fix: making allowModsToUnmuteUsers=true work again

When listen only fallbacks from Kurento to FreeSWITCH, we must guarantee
the muted alert won't be created, speciallly because listen-only's fallback
uses a flow similar to microphone's. Client currently crashes when this
happens: this commit fixes this peoblem.

We now stop the MediaStream (cloned/dummy input stream) when this is not
needed anymore.
We don't create/clone a new MediaStream when it already exists.
Fixed eslint warning in muted-alert/component.jsx
