debounceWait is not working as expected in universal mode

[AndrewBogdanovTSS]

Version: 2.3.0

How to recreate:
Add

head() {
      this.$meta().setOptions({debounceWait: 50})
    },

into layouts/default.vue

Result:
All meta info is undefined. Page meta is not updated on router change.

Removing debounceWait fixes an issue

The head function is not really the place to change options, better to do that in a created hook or something like that.

[AndrewBogdanovTSS]

@pimlie strange, as far as I remember, you've been recommending to do this in head()

[pimlie]

But still it shouldnt error out, there seems to be a regression now when you dont return anything in head/metaInfo

[AndrewBogdanovTSS]

I see...the fact that I used head() without returning anything caused an override of the internal components head() data, right?

[pimlie]

no, the issue is that vue-meta returns early when the result is not an object but that also means child components wont be traversed.

Have a fix ready, just trying to add a test for it now

See linked pr

@pimlie so it would be safe to set options in head() after this PR?
Do you recommend to still set them in created hook or it's better to be done in head ?

[pimlie]

Changing options should be done outside of the metaInfo / head function. That is specifically meant for collecting meta info and can be called many times during the lifecycle of a Vue app.
