Fix PaperSelect error message

[wukongrita]

Hi @miguelcobain ,
This will add the error message to show on PaperSelect component ( issue #1158 )
So the error message will appear at the bottom of the PaperSelect, like so:

Thank you, @wukongrita.
The problem with this is that it just renders the passed in errors.

You should use this.validationErrorMessages instead, that contains the manually passed in errors as well as other custom validation errors.
This was indeed a regression. Here is how it looked like before the refactor:

Can you please update this PR?

Something like adding:

.

.
    @noMatchesMessageComponent="paper-select/no-matches-message"
    @searchMessageComponent="paper-select/search-message"
    @onClose={{this.close}}
    @onOpen={{this.open}}
    @onFocus={{this.focus}}
    @onBlur={{this.blur}}
    as |opt term|>
    {{yield opt term}}
  </PowerSelect>

  {{#unless hideAllMessages}}
    <div class="md-errors-spacer">
      {{#if maxlength}}
        <div class="md-char-counter">{{renderCharCount}}</div>
      {{/if}}
    </div>
    {{#if isInvalidAndTouched}}
      <div class="md-input-messages-animation md-auto-hide" ng-messages>
        {{#each validationErrorMessages as |error index|}}
          <div id="error-{{inputElementId}}-{{index}}"
          class="paper-input-error ng-enter ng-enter-active" ng-message>
            {{error.message}}
          </div>
        {{/each}}
      </div>
    {{/if}}
  {{/unless}}

</md-input-container>

at the addon/components/paper-select/template.hbs ?
