Current behavior
When the p-datatable attribute metaKeySelection is set to false and selectionMode is set to single, no row data is emitted on row selection

Expected behavior
Emission of row data should occur if metaKeySelection is set to false

Minimal reproduction of the problem with instructions
Create a datatable with metaSelectionKey="false" and selectionMode="single" (see aforementioned plunker)

What is the motivation / use case for changing the behavior?
Users should be able to click on a row to unselect, not have to use ctrl/command to unselect

Please tell us about your environment:
MacOX, IntelliJ 2017
