Improve ui and unit tests

[stefanosiano]

📜 Description

removed ui test EnvelopeTests.checkProfileNotSentIfEmpty. Added unit test with same goal: SentryEnvelopeItemTest.fromProfilingTrace with empty file throws
added description messages to eventually failing benchmark tests
added small sleeps in SentryWrapperTest to avoid race conditions

#skip-changelog

💡 Motivation and Context

This should greatly reduce CI flakyness

💚 How did you test it?
