Tabs components instance added twice

[Caven Kathiresu]

Describe the bug
In the source code, the method addInstance is called twice in the Tabs class constructor (line 42, 43 in src/components/tabs/index.ts).
This creates a warning message in the browser when i try to create an instance and put the override options to true.
