In "run_seed_comparison_test.py" and "run_vadere_console_with_all_scenario_files.py", increased timeouts to avoid errors during CI pipeline.

Further changes:
- Renamed test directory "TESTOVM" to "TestOVM".
- Renamed test directory "TestOSM_Group" to "TestOSMGroup".

Maven's JaCoCo plugin version 0.8.3 newly uses a whitespace character to separate numbers and percentage sign.
Therefore, adapted regular expression.

In "run_vadere_console_with_all_scenario_files.py", enabled print statements in "run_scenario_files_with_vadere_console()" again.

Also added method "print_summary()".

In "run_vadere_console_with_all_scenario_files.py", marked three additional scenarios as long-running tasks.

The three scenarios are:
- basic_4_1_wall_gnm1
- thin_wall_and_closer_source_nelder_mead_ok
- thin_wall_and_closer_source_pso_could_fail

In "run_vadere_console_with_all_scenario_files.py", set timeout of long-running scenarios to 480 seconds and added "TestSFM" to long-running scenarios.
