[NDB PERMISSION_DENIED error] Fix trusty stacktrace on ANDROID_EMULATOR

[IvanBM18]

This PR comes as a need after the revert of this #5339 PR which introduced short circuit mechanisms to avoid DB queries, this however proved to provoke issues, so short circuit is no longer an option to fix any PERMISION_DENIED erros.

When we run jobs with an ANDROID_EMULATOR jobs, they all fail after executing a testcase. This happens because ANDROID_EMULATOR platform goes trough some legacy code(before the pre/main/pos separation of tasks) which expects the current bot to have access to DB or GCS.

This error only appear for uworkers and doesn't happen for pre-emptible bots. Because pre-emptibles do contain a trusted service account, where as uworkers dont.

Changes

• When entering the process in which we analyze the stacktrace we now check if we can process this stacktrace or not, validating the kind of bot we are at.
• Creates Unit tests for this new edge cases

Test performed

Changes initially present in dev since July 13th, and it didn't seem to non brake anything under ANDROID_EMULATOR jobs. Now for ANDROID_EMULATOR jobs.
