Bug 33972: Set importing status to batch outside of transaction

This patch moves the setting of the 'importing' status for the batch
outside fo the transaction.

This prevents a scenario seen on some setups where a deadlock is created:
background_jobs_worker.pl: C4::ImportBatch::SetImportBatchStatus(): DBI
Exception: DBD::mysql::db do failed: Lock wait timeout exceeded; try restarting
transaction at /usr/share/koha/lib/C4/ImportBatch.pm line 717

To test:
1 - Apply patch
2 - Stage and import some files
3 - Confirm the imports successfully complete
