The problem would occur when the `ForkedProjectLink` was deleted, but
the `ForkNetworkMember` was not. The delete would be rolled back and
retried.

But the error would not be saved because `Project#forked?`
would still be true, because the `ForkNetworkMember` exists. But the
`Project#forked_project_link` would be `nil`. So the validation for
the visibility level would fail.

Closes #38236

See merge request gitlab-org/gitlab-ce!14869

We can currently reduce the number of times we specify the tag of a
given example group by moving them hoisting them up one level to the
containing `feature`

This was added as part of the previous filtering via RSpec::Config.  It
should have been removed previously as part of moving the logic to
specify the tags we wanted in Specs::Runner

Previous efforts were aimed at detecting N + 1 queries, general
regressions are hard to find and mitigate.

When a build is retried automatically, we close any open todos. However, we do
that _before_ creating a new build failed todo.

To solve this, we check if the build is retried before creating the todo. We
also ensure that the build _instance_ has the correct attribute set, without
needing to reload it from the database.
