topic: drop _cleanup_tns_file(), move code directly into wlock()

This way we don't even have to make any assertions about wlock status. This
should be safe, since we have the wlock and it's held, and other processes
cannot acquire it and start messing with wdir, but we're also not inside any
context managers that could be using the wlock, so it cannot be suddenly
released either.

hg evolve --continue and obsmarkers after conflict resolution with no changes to commit (issue5967)

Amending revision 0 in a way that causes conflicts

  $ hg prev
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [0] apple
  $ echo apricot > a
  $ hg amend -m 'apricot'
  1 new orphan changesets

  $ hg glog
  @  2: apricot
  
  *  1: banana
  |
  x  0: apple
  

Trying to evolve, then manually discarding changes from revision 1

  $ hg evolve
  move:[1] banana
  atop:[2] apricot
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved merge conflicts
  (see 'hg help evolve.interrupted')
  [240]

  $ echo apricot > a
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg evolve --continue

This will correctly notice that revision 1 can be dropped

  $ hg evolve --continue
  evolving 1:dd9b5dd30cd6 "banana"
  evolution of 1:dd9b5dd30cd6 created no changes to commit
  $ hg glog
  @  2: apricot
  

This is important: 1 should not have a successor (especially not revision 2)
