This PR fixes a performance problem when reviewing a pull request in a
big instance which have many records in the `review` table.
Traditionally, we should add more indexes in that table. But since
dismissed reviews of 1 pull request will not be too many as expected in
a common repository. Filtering reviews in the memory should be more
quick .

Resolve#31492
The response time for the Pull Requests API has improved significantly,
dropping from over `2000ms` to about `350ms` on my local machine. It's
about `6` times faster.
A key area for further optimization lies in batch-fetching data for
`apiPullRequest.ChangedFiles, apiPullRequest.Additions, and
apiPullRequest.Deletions`.
Tests `TestAPIViewPulls` does exist and new tests added.
- This PR also fixes some bugs in `GetDiff` functions.
- This PR also fixes data inconsistent in test data. For a pull request,
the head branch's reference should be equal to the reference in
`pull/xxx/head`.
If the assign the pull request review to a team, it did not show the
members of the team in the "requested_reviewers" field, so the field was
null. As a solution, I added the team members to the array.
