DTGOV-209 Update the ProcessesPage UI to also include deployed workflows...

https://issues.jboss.org/browse/DTGOV-209
This should just call "setValue()" on the workflowsTable.  That's the reason for the widget to implement the HasValue interface to begin with.  The addRow() method should not be visible and should not be called.  There should be no need to call "clear()" here either - the method should just be this:

```
protected void updateWorkflowsTable(List<Workflow> data) {
    this.workflowsSearchInProgressMessage.setVisible(false);
    if (data != null && data.size() > 0) {
        this.workflowsTable.setValue(data);
        this.workflowsTable.setVisible(true);
    } else {
        this.workflowsNoDataMessage.setVisible(true);
    }
}
```
