commits_table: fix '...' commit message expand box

RenderCommitMessageLinkSubject should be called with .Summary, not
.Message, since it strips all but the first line and loses the </a>
that's needed for the HTML to be valid. As a result, the '...' button is
a link to the full commit and behaves badly.
