Vue 2.5 triggers warning of deprecated usage of scope instead of slot-scope
See for example:
```
(Emitted value instead of an instance of Error) the "scope" attribute for scoped
slots have been deprecated and replaced by "slot-scope" since 2.5. The new
"slot-scope" attribute can also be used on plain elements in addition to
<template> to denote scoped slots.
```
It should be as easy as updating the attribute name from `scope=` to `slot-scope=`
