exceptions: change error message for CommandFailedError

For the convenience of user, print the command that led to CommandFailedError in error message as a str than as a list or a tuple. This makes it more readable and enables the user to copy and use the command without any hassles. Signed-off-by: Rishabh Dave <[email protected]>
