EmptyViewTemplate does not do anything

[mattleibow]

Description

While looking at #15158, I was not able to test the layout as it was using EmptyViewTemplate. I saw this PR that fixed empty views #11763 for issue #10819.

However, now that EmptyView is working we closed it, but the other issue of templates is still outstanding.

Steps to Reproduce

1. Copy the repro in Android EmptyView in CollectionView weird resize after screen rotation #15158
2. Run
3. Observe nothing
4. Change the repro to use EmptyView
5. Observe the layout

Or

1. Download the sample in Android - Collectionview EmptyView not visible #10819
2. Run
3. Observe the empty view
4. Change the sample to use a EmptyViewTemplate
5. Run
6. Observe nothing

is this fixed? is there a workaround that we can use?

update: if you set the empty view property of the collectionview as empty like this way: `` <CollectionView
Grid.Row="2"
EmptyView=""
and this will show the emptyviewtemplate

I was able to solve the issue by setting a margin within the EmptyView:

                    <CollectionView.EmptyView>
                            <StackLayout Margin="0,50,0,0"
                                         HorizontalOptions="CenterAndExpand"
                                         VerticalOptions="CenterAndExpand">
                                <Label Text="No results matched your filter."
                                       Margin="10,25,10,10"
                                       FontAttributes="Bold"
                                       FontSize="18"
                                       HorizontalOptions="Fill"
                                       HorizontalTextAlignment="Center" />
                                <Label Text="Try a broader filter?"
                                       FontAttributes="Italic"
                                       FontSize="12"
                                       HorizontalOptions="Fill"
                                       HorizontalTextAlignment="Center" />
                            </StackLayout>
                    </CollectionView.EmptyView>
