diff-merges: move checks for first_parent_only out of the module 

The checks for first_parent_only don't in fact belong to this module,
as the primary purpose of this flag is history traversal limiting, so
get it out of this module and rename the

diff_merges_first_parent_defaults_to_enable()

to

diff_merges_default_to_enable()

to match new semantics.
