Not necessary here ot use ifEmpty.
Simply move the wrap to TMENU instead of HMENU.

lib.sidemenu = HMENU
lib.sidemenu {
    entryLevel = 2
    1 = TMENU
    1 {
        wrap = <div id="sidenav"> | </div>
        noBlur = 1
        NO = 1
        ACT = 1
    }
}

TMENU wrap will wrap only, if there are items in the menu.
