Don’t show “Scheduling tasks” indexing status when we are currently performing indexing

Switching from eg. `Indexing 76 / 148` to `Scheduling tasks` produces noise and provides little value to the user – on the contrary, it hides the indexing progress. Thus, prefer showing `Indexing x / y` over `Scheduling tasks`.
