Vue Warn: direct mutation of `existingTags`

[homersimpsons]

Hello, thank you for your awesome component.

I'm using it on a project and came across an issue (that do not break anything).

When using typeahead-url Vue shows a warning:

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "existingTags"

I guess this is because of the assignation here at least

vue-tagsinput/src/VoerroTagsInput.vue

Line 504 in e4ef0fb

that.existingTags = JSON.parse(xhttp.responseText);

Oh, yeah, you're right Thanks, I'll take a look when I have time.

Will be fixed in the next release.
