D10258: reabase: call rewriteutil.precheck() a bit later

REVISION SUMMARY
  We now filter out descendants of divergence-causing commits in
  `_handleskippingobsolete()`. The filtered-out commits are removed from
  the rebase set (`destmap` and `state`). We should therefore call
  `rewriteutil.precheck()` after `_handleskippingobsolete()`. This patch
  does that. It hasn't mattered so far because `rewriteutil.precheck()`
  doesn't yet check for divergence, but it will soon.
 
  This affects one test where we now fail because the user is trying to
  rebase an ancestor instead of failing because they tried to rebase a
  public commit. We have several similar tests just after, where we
  still fail because of the phase, so that seems fine. The difference in
  behavior also seems fine to me.
