cmdutil: avoid wrapping ctx.phasestr() by _()

This wrapping seems meaningless, because:

  - there is no "_()" invocation to prepare for extracting phase names
    to be translated

    "make update-pot" doesn't extract msgids for phase names

  - phase names are kine of reserved keywords like as branch name "default"
