currentRoute in preFetch SSR mode get params undefined

[ysya]

Describe the bug
When using object of currentRoute in preFetch will get undefined, need to use currentRoute.value to access object in currentRoute, but currentRoute don't have 'value' in typescript.

To Reproduce
Steps to reproduce the behavior:

1. Create quasar app in ssr mode and make preFetch: true in quasar.conf.js
2. add state test and mutations 'setTest' in vuex
3. use preFetch in vue file and call mutations setTest to set currentRoute.params to state test
4. console log vuex test onMounted

Expected behavior
don't need to add .value and things in currentRoute should not be undefined
