cli: Avoid storing empty lines in command history
When the console manager is run in the interactive mode, it also saves
empty lines (i.e. the Enter key is pressed without running a command) in
it's command history. Avoid this by processing the line only if
readline() returns a non-empty string. Makes it easier to navigate the
history using arrow keys.
