Ancestors: Protocols-ct.86

Fix: Lexicons ("browse protocol") started out with just [a number] as the window title.

Since October 2020 the window titles of MessageSets (a Lexicon is a MessageSet) contain the indication of the number of (filtered) messages. See uses of the windowLabel instance variable of MessageSet. Model windows observe the #windowTitle property by default. The MessageSet implementation uses the windowLabel instance variable. But Lexicon was not updated to set that variable, or to override windowTitle, so the title stayed essentially blank except for the number indicator.
