run/test endpoint does not return successful tests

[lukaszwawrzyk]

Take a look at this test: https://github.com/VirtusLab/intellij-pants-plugin-tests/blob/master/tests/src/test/scala/org/virtuslab/tests/pants/RerunFailedTestsTest.scala#L29 The call to runTestsFromGenerated should return 1 failed and one passed test, but it returns only the failed. There must be something wrong with our method of collecting results. It might be related to the fact that UI doesn't show the passed test by default.
