Introduce more optional chaining in the src/core/ folder

Browse source 
After PR 12563 we're now free to use optional chaining in the worker-thread as well. (This patch also fixes one previously "missed" case in the `web/` folder.)

For the MOZCENTRAL build-target this patch reduces the total bundle-size by `1.6` kilobytes.
