Fix ha-tabs chevrons bug

[RoboMagus]

Proposed change

As #16091 has not been touched since the issue was first created 4 releases ago, this proposes a workaround to fix the bug of scrolling chevrons appearing on the ha-tabs bar when they are not required. This is done by calling the scroll handling functions when the tabs are changed (populated).

This also fixes a non-reported bug that may occur in edge cases where by selecting a partially visible tab that causes the ha-tabs container to scroll that item into view, the chevrons are not updated while they should be, as now tabs have scrolled out of sight.
