Use ink_rect's width and set alignment before getting dimensions

[mohad12211]

1. Set the layout alignment before getting the box dimensions (ink_rect, logical_rect) = layout.get_pixel_extents()

   • This should fix Right Align Text No Longer shown in 0.7.9 #368

2. use ink_rect.width instead of logical_rect.width

   • If you use the logical rect, for some special RTL cases, the text would be over the avatar or very close to it.
   • I noticed that the commit that made the Right Align Text No Longer shown in 0.7.9 #368 regression (369ba96) was trying to solve some RTL issue, so I also tried to tackle this as well, there might be more RTL issues, but it should be better now.
