client: Fix comparing current prompt against previous 

We'd add the new command propmpt to history if it was different from
what current_history() returned which may not be the last command
executed, so we'd possibly add multiple identical commands to history
and skip some that were new.  Instead compare against
history_get(last index).
Also remove an always-true part of the condition on the next line.
