[PATCH 1/1] wt-status: use rename settings from init_diff_ui_defaults

["Eckhard S. Maaß" <eckhard.s.maass@xxxxxxxxxxxxxx>]

Since the very beginning, git status behaved differently for rename
detection than other rename aware commands like git log or git show as
it has the use of rename hard coded into it.  After 5404c116aa ("diff:
activate diff.renames by default", 2016-02-25) the default behaves the
same by coincidence, but a work flow like

    - git add .
    - git status
    - git commit
    - git show

should give you the same information on renames (and/or copies if
activated) accordingly to the diff.renames setting.

With this commit the hard coded rename settings are dropped from the
status command.
