[se-edu#459] Remove unnecessary pauses after pressing keys with GuiRo…

…bot (se-edu#572)

guiRobot#type(...) and guiRobot#push(...) internally pauses after
pressing the given keys.

We do not need to call guiRobot#pauseForHuman() ourselves after calling
these two key pressing methods.

Let's remove the redundant guiRobot#pauseForHuman() calls.
