delta-find: move the emotion of parents in a dedicated method

After splitting the filtering, and with the `_candidate_groups` layer removed,
we can start splitting the group generation too. This helps to organize this
code and make it easier to modifying the future.

#require test-repo

Set vars:

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ CONTRIBDIR="$TESTDIR/../contrib"

Prepare repo:

  $ hg init

  $ echo this is file a > a
  $ hg add a
  $ hg commit -m first

  $ echo adding to file a >> a
  $ hg commit -m second

  $ echo adding more to file a >> a
  $ hg commit -m third

  $ hg up -r 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo merge-this >> a
  $ hg commit -m merge-able
  created new head

  $ hg up -r 2

  perf extension - helper extension to measure performance
  
  Configurations
  ==============
  
  "perf"
  ------
  
  "all-timing"
      When set, additional statistics will be reported for each benchmark: best,
      worst, median average. If not set only the best timing is reported
      (default: off).
  
  "presleep"
    number of second to wait before any group of runs (default: 1)
  
  "pre-run"
    number of run to perform before starting measurement.
  
  "profile-benchmark"
    Enable profiling for the benchmarked section. (The first iteration is
    benchmarked)
  
  "run-limits"
    Control the number of runs each benchmark will perform. The option value
    should be a list of '<time>-<numberofrun>' pairs. After each run the
    conditions are considered in order with the following logic:
  
        If benchmark has been running for <time> seconds, and we have performed
        <numberofrun> iterations, stop the benchmark,
  
    The default value is: '3.0-100, 10.0-3'
  
  "stub"
      When set, benchmarks will only be run once, useful for testing (default:
      off)
