fix(vcs): let Commit and Shelf tree names use the whole row width (#1396)

Tree names in the Commit and Shelf windows were capped at 75% of the row, so long folder names were truncated with empty space left over. Names now take the whole row and the grey detail after them is truncated first. Fixes #1367
