fix of "options" unavailable issue

[rx-837]

As can I see property "options" is declared in interface "GlobalVTooltip" types/index.d.ts:

export interface GlobalVTooltip {
  enabled?: boolean
  options?: Partial<GlobalVTooltipOptions>
}

declare const vToolTip: PluginFunction<Partial<GlobalVTooltipOptions>> & GlobalVTooltip;
export default vToolTip;

but is lost in code src/index.js:

const plugin = {
  install,

  get enabled () {
    return state.enabled
  },

  set enabled (value) {
    state.enabled = value
  }

....

export default plugin
}

@Akryum omg... but it doesn't work

In my case i register only directive:

import Vue from "vue"
import vTooltip, { VTooltip } from "v-tooltip"

vTooltip.options.defaultHideOnTargetClick = false
Vue.directive("v-tooltip", VTooltip)

vTooltip.options is undefined and code is aborted with TypeError:

Uncaught TypeError: Cannot set property 'defaultHideOnTargetClick' of undefined

Quote from "README":

Or directly on package:

import VTooltip from 'v-tooltip'
VTooltip.options.defaultHtml = false

@Akryum

my fix is similar to https://github.com/Akryum/v-tooltip/blob/master/src/directives/v-tooltip.js#L218

in this case object "plugin" have "options" property with link on "defaultOptions"
