New libsvn_delta dependencies in tests

Hi All,

I noticed as I was building this morning that since we now have the
default editor (thanks all), every test project which has a LDADD of the
test_editor, now also needs libsvn_delta. We can fix this one of two
ways.

1) Put the @SVN_LIBSVN_DELTA_LIBS@ in the LDADD for each test the uses
@SVN_TESTS_EDITOR_LIBS@ in each Makefile.am that needs it or

2) Change the definition of @SVN_TESTS_EDITOR_LIBS@ to automagically
include libsvn_delta.la, since it will always be required.

What are people's preferences?
