Initialization errors with bootstrap-vue components

[paweld2]

Hello.

When using vuex-pagination with bootstrap-vue, specifically component <b-form-input>, there is an error on the initialization of vuex-pagination:

Cannot read property 'selectionStart' of undefined
    at VueComponent.get (form-selection.js?10fc:10)
    at VueComponent.computedGetter [as selectionStart] (vue.runtime.esm.js?2b0e:4842)
    at eval (index.js?2896:64)
    at Array.forEach (<anonymous>)
    at VueComponent.created (index.js?2896:63)

The error is because the property selectionStart uses a not initialized reference to the input field:
https://github.com/bootstrap-vue/bootstrap-vue/blob/dev/src/mixins/form-selection.js#L8

on the vuex-pagination code, the problem is that all the properties are retrieved to verify if there are a instance of vuex-pagination:
https://github.com/cyon/vuex-pagination/blob/master/index.js#L64

Does it make sense to change vuex-pagination logic to verify a optional marker on the components, like 'this.enableVuexPagination' to search for instances?

Hi @paweld2, thanks for the issue and the pull request.

The whole goal of checking for the _meta attribute on computed getters was, that it's simple to use and doesn't require manual initializing. But i see that this can be a problem in some cases.

However, i'm sure we could solve that in a way that would not require an additional argument like enableVuexPagination.

I'll look into it but let me know if you know anything!

@paweld2 I found a way to easily solve this, check 1807db0 and 0990031. It's already released as 1.2.9.
