Repeatedly deleting the same file in generated PRs

Several of the PR's generated (and now closed) as part of:

https://github.com/mgifford/o-hat-scanner

deleted the same file [‎site/trends.html‎](https://github.com/mgifford/o-hat-scanner/pull/23/changes#diff-1706e21f20dd8b34a1ce279fed8959a5e5609a2c2d6c162be04240af35c67499)

https://github.com/mgifford/o-hat-scanner/pull/23

Not sure how to address this, as I don't know what is wrong with ‎site/trends.html‎

Maybe it just should have been part of one of the pages scanned? Not sure.

But the accessibility scanner should be a little less trigger happy about including files to be deleted in the PRs that they are creating.

首先查看 PR 23 中的更改，尤其是反复删除 site/trends.html 的情况，然后追踪负责组装生成的 pull request 的 scanner 入口点。确定为什么在已关闭的 PR 中会选择同一个文件。完成的标准是生成的 PR 不再反复包含该删除操作；如果找到现有的测试位置，还应为该行为添加覆盖。
