[Logging] Add testcase-based log context to analyze, blame and impact tasks

[ViniciustCosta]

• Added the testcase-based structured logs to the analyze, blame and impact tasks.
• Added the task logs context decorator to a missing entry point for trusted tasks.
• Reverted some changes in symbolize task where the private methods I had created (e.g. _utask_postprocess) were receiving the testcase as argument (because it was already retrieved for the logs context). However, this could create an issue if, in the original method, the testcase was updated before the get_testcase.

Is there any tests we can add for it?

This didn't change anything in the logs, just instrumented the remaining tasks, so I don't think we can add tests for this (at least considering the as is of the tests).

That's fair!
