moved assertions after "assume" call

📜 Description

moved assertions after "assume" call

#skip-changelog

💡 Motivation and Context

The checkEnvelopeProfiledTransaction test is already skipped on headless emulator (agp matrix), but some assertions were done before the assume call, which is the one that skips the test. So sometimes those assertions could throw in the agp matrix workflow.
Fixes issues like https://github.com/getsentry/sentry-java/actions/runs/6814073423/job/18530091061?pr=3036
