Flush NewContents cache in CheckPatchFormatted

Prior to https://crrev.com/c/5740609, NewContents never flushed cache
so the second NewContents() would always produce the same contents
post-yapf as as pre-yapf. Flush cache on second NewContents() call to
get updated file contents. Also fix the formatting a bit.
