Fix job progress item title styles

This makes the title properly ellipsize when collapsed (along with
removing the redundant collapsed style).

This also fixes the title not taking up enough space sometimes. Without
the constrainedHeight property, the layout sometimes doesn't accomodate
for changes in the textView's height.
