Slight refactoring and test fixing.

* bzrlib/tests/test_merge.py:
(TestMergerEntriesLCAOnDisk.test_modified_symlink): Passing now.

* bzrlib/merge.py:
(Merge3Merger._lca_multi_way): Fix doc reference.
(Merge3Merger.merge_contents.contents_conflict): Try to delay
this_pair evaulation to avoid unnecessary sha1 (impyling file read
from disk) calculation. Also slightly refactor to avoid repeated
file_id in trees calculations.
