Console error when only some tabs set the tab attribute

Check existing issues

[X] I have checked for existing issues to avoid duplicates

Actual Behavior

A console error appears on initial load when not all tabs in a group set the tab attribute. This doesn't seem to affect the functionality of the component, but it is a bad look in this specific case.

Expected Behavior

No console error appears.

Reproduction Steps

For some reason Codepen doesn't show the console error (at least for me) so the best way to reproduce this is to paste the following HTML into a demo.html file and run npm start with the devtools console open:

<calcite-tabs>
  <calcite-tab-nav slot="title-group">
    <calcite-tab-title closable tab="Watercraft">Watercraft</calcite-tab-title>
    <calcite-tab-title closable>Automobiles</calcite-tab-title>
    <calcite-tab-title closable>Aircrafts</calcite-tab-title>
  </calcite-tab-nav>
  <calcite-tab tab="Watercraft">
    <calcite-notice icon="embark" open>
      <div slot="message">Recommended for coastal use</div>
    </calcite-notice>
  </calcite-tab>
  <calcite-tab>
    <calcite-notice icon="car" open>
      <div slot="message">A good choice for inland adventure</div>
    </calcite-notice>
  </calcite-tab>
  <calcite-tab>
    <calcite-notice icon="plane" open>
      <div slot="message">Cross continents quickly</div>
    </calcite-notice>
  </calcite-tab>
</calcite-tabs>

The following error is shown on initial load:
