Row should call getRowStyleClass even if table is scrollable

[benjamincharity]

This fixes #1613

Bug:

Plunkr demo: http://plnkr.co/edit/25NZ7M?p=preview

Current behavior

If the table has [scrollable] set to true, the method passed to [rowStyleClass] is never called. If the table is not scrollable, the method is called as expected.

Expected behavior

The method passed to [rowStyleClass] should be called for every row; even if the table is scrollable.

Minimal reproduction of the problem with instructions

Plunkr demo: http://plnkr.co/edit/25NZ7M?p=preview

1. Define a table with scrollable set to true:
2. Pass a method to rowStyleClass that should be called with row data:

<p-dataTable [value]="items" [scrollable]="false" [rowStyleClass]="tableOneHighlight">
    <p-column field="id" header="ID"></p-column>
    <p-column field="name" header="Name"></p-column>
</p-dataTable>

What is the motivation / use case for changing the behavior?
I need to add a custom class to rows even when inside a scrollable table
