tests: fix for failure of test-convert-p4-filetypes.t

Before this patch, test-convert-p4-filetypes.t fails (at least with
2015.2/1366233 version of p4/p4d), because some files below are
omitted in expected output for revision 1.

  - file_tempobj
  - file_xtempobj

These files are:

  - add-ed at revision 0, and
  - edit-ed at revision 1

According to perforce command reference below, file type 'tempobj' and
'xtempobj' imply '+S' modifier, which indicates that "Only the head
revision is stored". This means that these files should appear only in
the most recent revision (= revision 1).

BTW, test-convert-p4-filetypes.t with 2015.2/1366233 version of p4/p4d
fails similarly also at recent revisions for hgext/convert/p4.py in
2015. Therefore, this patch should be reviewed by perforce guru, to
examine whether this failure depends on version (and/or configuration)
of p4/p4d or not.
