Adapted three scenario files for salient behavior (use random seed and spawnAtRandomPositions=true).

Salient behavior

See merge request !68

Used following commands:
- mvn -Dmaven.test.skip=true package
- java -jar VadereSimulator/target/vadere-console.jar migrate -r VadereModelTests/
- git clean -n
- git clean -f (to delete <scenario_file>.scenario.legacy which is created by migration assistant)

# Conflicts:

change the metric notebook, small changes to the postvis such that other simTimeSteps not equal to 0.4 will be used if they are contained in the postvis.trajectories file.

Resolve "Include to every header name the processor id"

Closes #246

See merge request !67

Merge branch '246-include-to-every-header-name-the-processor-id' of gitlab.lrz.de:vadere/vadere into 246-include-to-every-header-name-the-processor-id

Renamed "JsonTransformV8ToV9" to "JsonTransformV9ToV010" to avoid naming conflict when merging with master.

In "run_vadere_console_with_all_scenario_files.py", store log files in subdirs (e.g., "TestGNM", "TestOSM" etc.).

Tools/ContinuousIntegration/run_vadere_console_with_all_scenario_files.py:
- Argument parser uses a **positional**, but optional, argument to run a single scenario file instead of an **optional** argument provided with `--scenario <name>`.

Tools/collect_line_and_branch_coverage.py:
- Deleted this duplicated file.

# Conflicts:
#	VadereState/src/org/vadere/state/simulation/VTrajectory.java

In "VTrajectory", method "duration()" returns an "Optional<Double>" instead of "double" (required if trajectory is empty).

In "VTrajectory", added workaround to avoid "NullPointerException", but workaround leads to corrupt output file.
