move TestBugInSomething to analysis.tests

This test is setup to reproduce complex failures from TestRandomChains,
e.g. it has SopFilter and other tools for debugging. But it still
resides in the analysis/common module and currently can't be used to
debug any TestRandomChains failures that use other modules (e.g. icu).
