Stan Hu 6fa5f510e8 Guard against deleted project feature entry
In https://gitlab.com/gitlab-org/gitlab-ce/issues/66482, we see that a
project's `project_feature` association may be lazily loaded and hence
return `nil` if the entry is deleted if the `Project` is already loaded
in memory. To ensure we don't fail hard when this happens, assume all
features are disabled.

We can fix this issue by eager loading the `project_feature` in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32169, but we
shouldn't have to depend on that.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/66482
