[RN] Don't tell everyone we're called "me"

Recently/as part of the work on taking into account the user defined by
JWT, the local participant (on mobile) started telling the remote
participants that he/she had the display name "me". Obviously, that's
incorrect. Do not store the default display name in redux. While it may
be argues that redux is the place for all states, base/participants and
the name property of Participant is not meant to be that display name
because that is being sent to remote participants, the default name
needs to be internationalized, etc. So it's better to not store the
default display name at this time at all because it's not used by mobile
anyway and Web already deals with remote participants who don't share
their display names.
