Create tags helper
In some cases it can be useful to build tag objects manually. For example, if you use the validation feature and pass unvalidated tags to vue-tags-input. It validates the passed tags and emits @tags-changed, if the user does a action.
But for the time between the mounted hook and the user action, the model holds unvalidated tags.
To solve this problem, you can create validated tags by yourself and pass them to vue-tags-input. To achieve that, we can import some helper functions from vue-tags-input.
