Props params passing with keep-alive

[defusioner]

Version

2.8.1 & 3.0.1

Reproduction link

https://codesandbox.io/s/mo5x4nlq7p

Steps to reproduce

• Open console
• Go to dog, then to home

What is expected?

Every route is in keep-alive, so dog should be kept alive with its name=dog

What is actually happening?

In console we see: missing required prop: "name".
For this demo it is almost transparent, but in a real project I've faced a problem that the component that is dependent of the incoming parameter won't be rendered (as it uses apollo and computed properties binded on that parameter).

P.S. Without keep-alive it's ok
