Enable 5 lines of Sidekiq backtrace lines to aid in debugging

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.
