Regression: Session timestamps ought not be updated on metadata-only changes.

[ariane-emory]

Description

When a session is renamed in the session list, its timestamp is updating causing it to unexpectedly jump in it's position in the session list.

I had previously corrected this behaviour in the long-since merged pr #9495, but that fix appears to have been clobbered by changes introduced in 6d95f0d.
