bug: Ionic/vue ionicons error

Bug Report

Ionic version:

[x] 4.x @ionic/vue@0.0.4 or @ionic/vue@next

Current behavior:

When updating vue apps developed with Ionic/vue@0.0.4 and running the

npm install 

after having deleted the node_modules folder, i got the following error

Uncaught TypeError: Cannot convert undefined or null to object
    at Function.keys (<anonymous>)
    at addIcons (chunk-ea2b3dce.js?d602:13)
    at appInitialize (ionic-vue.esm.js?481b:279)
    at Object.install (ionic-vue.esm.js?481b:687)
    at Function.Vue.use (vue.runtime.esm.js?2b0e:5101)

    at __webpack_require__ (app.js:767)
    at fn (app.js:130)
    at Object.1 (app.js:10267)  

Expected behavior:

Should be able to load ionicons. this was working perfect when @ionic/core@4.4.0 and ionicons@4.5.6 were dependencies. Now when you reinstall from scratch the dependencies are @ionic/core@4.6.0 and ionicons@4.5.10-2 and it is failing both for @ionic/vue@0.0.4 and @ionic/vue@next

Steps to reproduce:

• take an existing vue apps running with @ionic/core@4.4.0 and ionicons 4.5.6
• delete the folder node_modules
• delete the package-lock.json
• npm install

Just add ionicons@4.5.9-1 to your package.json. This just overrides any peer dependency and can be used as a workaround.

It is published on npm do npm install --save @ionic/vue@next
