Remove duplicate parameter filtering

The Active Job and Sidekiq instrumentations called out to our parameter
filtering. It doesn't need to do this. Our Transaction class runs it
through the parameter filtering when it calls `sanitized_params` when
sampling the transaction.

No test updates needed. There were already tests present it filtered out
parameters. It still does that.

[skip changeset] No behavior change, only an optimization.
