REVISION SUMMARY
  There are (more or less) valid cases when currentTerminalDisplay can be
  not set:
  
  - konsole started with `--background-mode`, sendText called via D-Bus
  - text send through KPart's sendInput()
  
  It can be assumed read-only is not set in this case.
  
  This patch should also fix TerminalInterfaceTest. Currently the shell
  probably doesn't get commands send through sendInput.

TEST PLAN
  - Run `konsole --background-mode --nofork & ; sleep 2; qdbus org.kde.konsole-$! /Sessions/1 sendText $'echo test\n'`
  - Press Ctrl+Shift+F12
  - The terminal should show `echo test` command and its result
