Unable to see errors when run command via context menu

[Chunosov]

For example:

• Make some intentional error in customizy.py of soft of some package.
• Find installed env of this package
• Select "Refresh env" from the context menu
  Nothing happens.
  But when we run ck refresh env:uid-of-this-env we can see customizy.py is called and it fails because of our error.
