Status bar does not update when in home directory or in another folder that's not sample foder

[KerrynEer]

Status bar updates only for changes inside the sample folder

Status bar does not update for changes in the home directory or inside another folder other than the sample folder.

I think the problem lies with the StatusBarFooter.java. The constructor of it takes in a CardFolder and assign the listener to it, so the listener is only for this sample folder and not new folders or in the home directory.

Screenshots shown below:
This command is done in the home directory at 4.23pm but status bar still shows 4.21pm (the previous update)

Similarly this command is done in another folder at 4.25pm but status bar is not updated
