Stop word-count extension from breaking extensions and command palette
Created by: tjkandala
Fix #10600 (closed)
Can now safely use the word-count extension. I implemented @felixfbecker's idea to swallow errors from spreading view contributions that are not iterable.
I have a 'backwards compatibility' fix for the word-count view schema stashed away, but I didn't include it because views were documented as arrays since they were introduced.
