adapt request-pull tests for new pull request format

10eb000 (request-pull: avoid mentioning that the start point is a
single commit, 2010-01-29), changed the pull request format, so the
test needs some changes to still pass:

 - tolerate a missing blank line between “in the git repository at:”
   and the name of repository and branch

 - recognize subject and date in the new request format

 - update the expected request template to match the new format
