In commit history list view, show all commits

Summary:
Currently, the last group of commits is not shown in the list view because the final `$list` is never added to `$view`.

For example, if the first page would contain commits from "April 7", "April 6", and "April 5", commits from "April 5" are not shown.

(If a repository has 100 commits in a single day, nothing is shown.)

On this server, here's the bottom of page 1:

{F4987087}

Here's the top of page 2:

{F4987088}

However, here's `git log` between those commits:

```

```

This group of commits does not currently appear anywhere in the list.

Test Plan: Viewed a page of commits, saw 100 commits.
