Exclude projects pending delete from notifications Make `NotificationSetting.for_projects` exclude projects that are excluded by the default scope on `Project`. (At the moment, that's projects with `pending_delete: true`.) See https://gitlab.com/gitlab-com/support-forum/issues/819 See merge request !5138
If the Sidekiq job fails for some reason, a project can be 'stuck' pending deletion. The project can't be viewed, so it shouldn't be available through the notification settings association as this will throw an exception when we try to show the link.
Escape file extension when parsing search results When a file extension contains characters which have a meaning in regular expressions, the search may crash. Fixes #18553 See merge request !5141
Show last push widget in upstream after push to fork ## What does this MR do? Show the last push widget in the upstream project when you push to a fork. ## Are there points in the code the reviewer needs to double check? In the view, I'm checking if `@project` in the first part of the conditional. I felt it was necessary in case `@project` wasn't an object in all cases. Will it ever not be there? Is this check necessary? Should there be tests? I don't see existing ones for this. ## Why was this MR needed? I use the fork workflow everywhere and it has annoyed me for some time that the last push widget doesn't show up when viewing the upstream project. I'm almost never viewing the fork in GitLab so I want to be able to easily create a MR in any case. ## Screenshots (if relevant) **Widget in upstream repo:**  **Widget in fork**:  **Widget on dashboard**:  See merge request !4880
