Won't fix

[dubinsky]

I did fix quite a number of bugs and made a number of improvements to various test frameworks; at this point, cosmetic fixes for the frameworks I do not even use are unlikely to happen, but let's at least list them:

• use sbt loggers in ZIO Test;
• add test summary in specs2;
• add test summary in Weaver Test on JVM;
• add test filtering in Weaver Test;
• add test summary in Hedgehog;
• add test filtering in Hedgehog;
• add test summary in AirSpec;
• add test filtering in AirSpec;
