Increase file collapsing threshold when vieweing diffs file-by-file
## Description When I'm reviewing a MR file-by-file, I'd expect to see the **whole** file like I do in my IDE :smile: | In GitLab file-by-file | In IDE | |----------|-------| | ![Screen_Shot_2020-09-18_at_12.58.32_PM](/uploads/4226367e93cd369ab556eef524c97015/Screen_Shot_2020-09-18_at_12.58.32_PM.png) | ![Screen_Shot_2020-09-18_at_1.00.20_PM](/uploads/f8faca4347f08ff32afecde96a548a41/Screen_Shot_2020-09-18_at_1.00.20_PM.png) | <small>Taken from this MR https://gitlab.com/gitlab-org/gitlab/-/merge_requests/42443</small> In this example :point_up:, I don't know if we are adding a `computed` or a `method`, but when I review locally all the context is right there. ## Proposal Let's smartly adjust the threshold of collapsing file content when reviewing file-by-file.
