convert: test clean p2 file missing

216fa1ba9993 introduced "clever" reuse of p2 but did that convert could fail
with
  abort: f1@f73e02ae52c5: not found in manifest!
when it tried to reuse a file from p2 but the file didn't exist there, for
example because filemap changes.

5ca587348875 fixed that (using changes from a75d24539aba), but with a quite
different reasoning and test case.

Add another test that makes sure this case is covered too.

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb
  adding b

  $ hg co -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
  [255]

Even with strange revset (issue4465)

  $ hg merge ::.
  abort: merging with a working directory ancestor has no effect
