[Bug]: Wrong setting of mainRenders in e_Render class

[Jimmi08]

What e107 version are you using?

Latest Github version (just updated)

Bug description

		private function getMainRender()
		{

			if(isset($this->mainRenders[0]))
			{
				return $this->mainRenders[0];
			}

			return array();

		}

Value on user profile with comments ON:

[mainRenders:e_render:private] => Array
        (
            [0] => Array
                (
                    [list] => 1
                    [uniqueId] => 
                    [menuArea] => 0
                    [menuCount] => 0
                    [menuTotal] => 0
                    [setStyle] => main
                    [caption] => 0 Comments
                )

            [1] => Array
                (
                    [list] => 
                    [uniqueId] => 
                    [menuArea] => 0
                    [menuCount] => 0
                    [menuTotal] => 0
                    [setStyle] => main
                    [caption] => Member Profile
                )

        )

How to reproduce

1. Set comments on user profile ON
2. check with the bootstrap5 theme

Workaround - just partial fix

	  {SETSTYLE=raw}
	  {PROFILE_COMMENTS}

result

Expected behavior

Comment tablerender shouldn't influence the main render

The problem with this is that if I set it this way, the caption does not appear. The caption cannot be overwritten with comments title.
