unified translations has a fundamental problem

[ThomasWaldmann]

While you see the receiver (no sender connected), it only shows placeholder labels instead of english or translated texts, pretty useless.

When a sender connects, you don't usually see the receiver app anymore as the screen contents now come from the sender. Not sure, maybe the receiver is now secretly displaying correctly translated text.

Workaround:

• if a translation cache exist, use the cache contents
• always update the cache with the received translations
