Empty Syles combo in filter sample

1. ​http://ckeditor4.t/ckeditor/samples/filter.html
2. See Styles combos of editor 2 & 3: they're empty.
3. This looks like:

To reproduce:

1. Get the latest major version
2. Reload cache in browser and load filter sample.
3. Styles dropdowns for 2nd and 3rd editor are empty.

Not a bug - feature. Combo is empty, because all styles available for current selection are disallowed by ACF. Select image and you'll see image's styles there.

But the issue still exists. To avoid confusion like yours we may add more rules for these editors.

Created branch ​t/10137:

• Created custom stylesSet for this sample so no stylescombos are empty.
• Removed unnecessary "editor 5" that was for testing purposes only and didn't reflect any filtering feature.

We don't need to set special styles set for filter sample. Default one is ok. Less changes make sample less confusing.

I pushed ​t/10137b which:

• adds ACRs for 2nd and 3rd editors which enable some of the default styles,
• removes editor5 which indeed is unnecessary - next one (based on h1 editable) is much better.

Fixed on major with ​git:516399f.
