[UI] Only show first line of commit throughout different views

[zanona (Marcus)]

This is probably just nitpicking, but I have noticed that after squash merging a PR with a lot of changes, the repos and branches view shows the entire commit message instead of just the first line? This is not the case for the activity feed though which shows as I’d expect.
See below:

Repos view (inlined trimmed message, tooltip still shows all commit msg)

Branches view (full commit msg)

Deployments view (full commit msg)

Activity view (no problem)
