Trace collected for single test, but fails on all test

[algomaster99]

For commit cdk/cdk@8469dd2, we generate non-empty trace for test org.openscience.cdk.structgen.maygen.MaygenTest::test_gettersAndSetters. However, when all tests are run, no trace is collected.

Command to reproduce:

java -jar main/target/collector-sahab-0.5.2-SNAPSHOT-jar-with-dependencies.jar -p /home/aman/testrepos/cdk -l  d5365ab -r 8469dd2f3f8d0361b4f3f05a6da9ad3098f41a87 -c tool/structgen/src/main/java/org/openscience/cdk/structgen/maygen/Maygen.java  --slug "cdk/cdk" --selected-tests org.openscience.cdk.structgen.maygen.MaygenTest::test_gettersAndSetters

mvn test runs on each module if all tests are executed. Whenever mvn test process shuts down, we output a trace. For multi-module project, this is WRONG because every time the trace is replaced and we lose information from previous modules.

This problem can be addressed when we output trace as line-delimited JSON for faster processing.
