Run filters on bad commit before blame/bisection

[shalinmangar]

We use the jenkins data to demote tests to detention and each such demotion is to be bisected to find the offending commit. However, for bisection to work we must be able to reproduce the test failure (unless it is a new test, in which case blame is a quick git log). We should run each demoted test against the configured filters and run blame only if the filters fail for this test. If the test passes our filters then we should mark the test somehow and indicate in the report{.json,.html} and skip running blame.

Now that #6 has been fixed, this issue can be closed. We use the reproducible flag and good sha recorded by changes made in this commit to run blame.
