Tracing and integration test tweaks (#3336)

* Disable image and document picker integration tests as they randomly fail to load and are flakey.

* Delete any pre-existing log files

* Various tracing tweaks and fixes:
- delete the custom tracing log levels as we can't control their ouput
- implement comparable on them
- change default levels only if the new chosen level increases their verbosity

* Make logging targets mandatory and fix their logging levels

* Switch back to using the `run_tests` reset simulator flag as `fastlane snapshot reset_simulators` was too generic and slow

* Switch all integration test taps to `tapCenter` (nee forceTap) after noticing missed taps on CI.

* Make the logging file prefix explicit, let the main app not use one.

* Rename tracing configuration `target` to `currentTarget`
