Flank should not skip tests annotated with @Ignored

[pawelpasterz]

Fixes #629

Changes

• tests annotated with @Ignore are included in test matrix by default (TL skips them anyway)
• user still can filter tests with @Ignore with notAnnotation org.junit.Ignore
• Ignored tests now have time = 0 (regardless previous results)
• update and refactor unit tests

Checklist

• Documented
• Unit tested

If we know a test is ignored, we probably want to assign it a runtime of 0 when packing shards by time.

Nice catch! Thanks for pointing this out
