BHV-7870: The right area of gridlist is covered by scroll bar

moon.DataGridList.updateBounds function uses only scroller's width value instead of padding-right value of scroller's client-wrapper
Annd scroller width is 60px and padding-right value is 70px. So, DataGridList's bound width becomes 10px bigger than value that it should be
```
list.boundsCache.width = w-v.hasNode().offsetWidth
```

```
.moon-scroller-client-wrapper.v-scroll-enabled {
  padding-right: 70px;
}
```
