Update InPlaceEditView.java for Enter Key issue 3850 (#3853)

Second attempt to fix issue #3850 , when the Enter key is pressed the TextField loses focus, now I have added this condition to the code that if it is a multi-line TextArea then when the Enter key is pressed it wraps maintaining the focus on the TextField instead if it is a single line TextField it enters the onEditorAction() function
