Enable 5 lines of Sidekiq backtrace lines to aid in debugging

Closes #27626

See merge request !13813

Customers often have Sidekiq jobs that failed without much context. Without
Sentry, there's no way to tell where these exceptions were hit. Adding
in additional lines adds a bit more Redis storage overhead. This commit
adds in backtrace logging for workers that delete groups/projects and
import/export projects.

Closes #27626

To protect master from surprise failures, as long as we continue to support MySQL.

Alternative fix for 422 when using standard login with ldap enabled

See merge request !13103

This column isn't always set (e.g. when upgrading from older instances)
and technically it could be NULL (e.g. when flushing the cache).

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/36919

This avoids loading the `OmniAuthCallbacksController` at boot time so
it doesn't mess up the `before_action`-chain
