v6.21.0-beta.1

• Get a better look at yourself while a 1-on-1 call is ringing. Individual video calls now use the same full-screen view that previously only appeared at the beginning of a new group call. When it comes to being consistent, we try to be persistent (not resistant) and now the discrepancy is nonexistent because these things are no longer different.
• We'd also like to express our appreciation to @complexspaces for their help and feedback while working on this release.
