Calendar tab in profile

Hi ,

Because of an oversight back in October 2019, both frio and vier themes started showing the "Calendar" tab in the user profile tab row, despite them explicitly forbidding this.

What should we do know?

• Keep the faulty behavior.
• Revert to the intended behavior.

I'm partial to the first behavior as it's now been more than two years with these links and nobody has complained, but I don't want to overstep the creators of either themes either.
