Unused code in WP_Widget_Links

[SergeyBiryukov]

As reported by pavelevap in #18096:

In Links widget there are two places with the same string, but I could not simulate to display one of them on my testing website?

if ( is_admin() && !$category ) {
	// Display All Links widget as such in the widgets screen
	echo $before_widget . $before_title. __('All Links') . $after_title . $after_widget;
	return;
}

This code was introduced in [10896] as a part of the fix for #9449. It doesn't make much sense, since the function is never called in the admin.

Thank you, Sergey.

In [20245]:

Remove dead code from the Links widget. Props pavelevap, SergeyBiryukov. Fixes #19179.

The widget() method isn't called on the admin screen.
