cmdutil: allow callers of cmdutil.dorecord to omit suggestion

Interactive committing under non-interactive mode shows command
suggestion, but sometimes it is meaningless.

  command      suggestion usability
  ------------ ---------- -----------
  record       commit
  commit -i    commit     meaningless
  qrecord      qnew
  qnew -i      qnew       meaningless
  qrefersh -i  qrefresh   meaningless
  shelve -i    commit     incorrect
  ------------ ---------- -----------

This patch allows callers of 'cmdutil.dorecord()' to omit meaningless
suggestion by passing None or so for 'cmdsuggest' argument of it.

This is a preparation for subsequent patches, which fix each
suggestion issues above.
