Fixups after conversion to Mercurial, fixing tests broken by the changes in the previous commit.

* Fixed differences in expected trace output caused by every test being
   wrapped in a transaction.
 * Fixed require-order bug in two of the specs
 * Corrected a mis-paste in the m17n spec before:all block
