Bug 27669: Fix 'importing' and 'reverting' statuses when importing/reverting a batch

SetImportBatchStatus is not called with $batch_id

It has been caught by bug 25026, and www/search_utf8.t fails with
t/db_dependent/www/search_utf8.t .. 14/87 Error POSTing http://koha:8081/cgi-bin/koha/tools/manage-marc-import.pl: Internal Server Error at t/db_dependent/www/search_utf8.t line 240.

And, from logs:

manage-marc-import.pl: C4::ImportBatch::SetImportBatchStatus(): DBI Exception: DBD::mysql::st execute failed: Truncated incorrect DOUBLE value: 'importing' [for Statement "UPDATE import_batches SET import_status = ? WHERE import_batch_id = ?" with ParamValues: 0=undef, 1='importing'] at /kohadevbox/koh
