feat(studyset): an empty tab says its material is in the topics, and leads there

Browse source 
People testing the app looked for the material of a studyset that groups
topics in its own empty tabs, which said "No flashcards yet" and how to
add some. A tab with none of its own while the topics hold some now says
so: "The flashcards are in its topics", each topic holding some with how
much (everything inside it counted), opening it; for flashcards Browse
all of them in one list; and, quieter, how to add some here after all.
Opened for the first time, such a studyset shows the first tab its topics
fill. The tabs' counts stay the studyset's own.
