LogAnalzer: Misc fixes for malformed log files & missing parameters

Hi @chapman,

This PR contains three independent commits, but they are non controversial and good ;-).
1) Fix formatting in the tests dir (similar to the automated change made at the root)
2) For tests that depend on parameters, treat missing params as a test failure
3) If skipping bad lines, ignore parsing errors on lines

Thanks to @cmavr8 for reporting this bug.  Fix #1268.
