Zim with no article leave temp files behind

[rgaudin]

with libzim.writer.Creator("test_x05.zim", main_page="A/index.html", index_language="fra", min_chunk_size=2048) as zim:
    pass

T:7; A:3; RA:0; CA:3; UA:0; FA:0; IA:0; C:0; CC:0; UC:0; WC:0

T:7; create title index
T:7; 5 title index created
T:7; 2 clusters created
T:7; write zimfile :
T:7;  write mimetype list
T:7;  write directory entries
T:7;  write url prt list
T:7;  write title index
T:7;  write cluster offset list
T:7;  write header
T:7;  write checksum
T:7; rename tmpfile to final one.
T:7; finish

and on the filesystem:

.rw-r--r--   24k reg  staff 10 Jun 13:33  test_x05.idx
drwxr-xr-x     - reg  staff 10 Jun 13:33  test_x05.idx.tmp
.rw-r--r--   50k reg  staff 10 Jun 13:33  test_x05.zim
.rw-r--r--   24k reg  staff 10 Jun 13:33  test_x05_title.idx
drwxr-xr-x     - reg  staff 10 Jun 13:33  test_x05_title.idx.tmp

zim file is working (albeit without actual article) but the xapian stuff is not removed.

The index are cleaned by the Creator destructor. This is probably because we don't correctly delete it :

• We have to fix this on python-libzim side.
• As we already have the issue with node-libzim, maybe it is time to change this on libzim side to clean those file at "finalize" step.
