monaco: recently used commands not displaying

[vince-fugnitto]

Bug Description:

I was finally able to identify the path that lead to the bug I noticed in #9727 (comment).

When we trigger the palette and type > (to trigger the quick-commands), we will not get the same recently used results as if we trigger F1 directly.

Steps to Reproduce:

1. ensure that you have a clean state
   • rm -rf ~/.theia
   • reset workbench layout
   • clear command history
   • close the application and restart
2. trigger the quick-open (ctrlcmd+p) and type >
3. execute a command, repeat for multiple commands
4. triggering the quick-open with ctrlcmd+p will not yield recently-used results
5. trigger F1 - the correct results will now appear
