Before this commit, if the user searched the command palette and pressed
the enter key without waiting for the rendering, then the command executed was incorrect.
The "inputPromise" promise used to know if the new commands were loaded correctly.
This one did not wait for the resolution "setCommands" called by "onSearchInput".
So we modified the "debouncePromise" utility to make sure that it waits for
the resolution of the function given to it before resolving its promise.
