[java-analysis] ProjectBytecodeAnalysis: do not rewrite null->x contract with _->x if notnull parameter was inferred

Fixes IDEA-354381 Unreachable code inspection fails when using Streamable.of()
Unfortunately, the test does not differentiate the bug. I failed to write a good test in a reasonable amount of time. Nevertheless, the original issue is fixed.
