kaltenbrunnermarkus 5f11d92458 Opening a design pins its body names, so the first undo evaluates nothing (#8939) ...

Problem: a design saved before body names were pinned (#6403) is pinned by its first command
that changes it, as part of that command. Undoing that command went back to the unpinned design,
whose fingerprints no evaluated result matched any more, so the first undo after opening
evaluated the whole timeline again: 63-72 s in the SELENE rover (5,484 features) when opened
from the command line or headless (`Session::opened_at`), 0.08 s with this change. `doc.open`
pinned at the end of the command instead, which kept undo fast but left the design with unsaved
changes on opening.

Solution: `Session::opened_at` pins the names as it opens the design, with the names the file's
bodies have (no result changes, so nothing is evaluated), and takes the pinned design as the
saved one: opening is no change.
