Naming mixin mixup

[elevatebart]

From @ale-grosselle,

https://github.com/ale-grosselle/vue-styleguidedist/blob/master/src/basic/button/ButtonMixin.vue

If a component does not have a name and is loading mixins, Docgen will use the name of the file of the mixins instead of the name of the file of the component.
