Ensure that new empty console line are really empty.

Browse source 
This fixes a corner case: When the client is in state `ca_disconnected`
and the user presses repeatedly return, there is a chance that a older
line is erroneously printed again. This is caused by spinning through
the console history buffer, when an old line is the current line a the
frame were the console refreshs it's printed. Work around that by
clearing every line as soon as it becomes the current line.

Closes #987.
