problem

Errors were not handled properly at one place in hotfolder import. That is leading to the direct deletion of the project which produced then follow up errors: 

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`DB1189`.`LEK_task_tm_task_association`, CONSTRAINT `LEK_task_tm_task_association_ibfk_2` FOREIGN KEY (`taskId`) REFERENCES `LEK_task` (`id`))

solution

Change the error handling so that this can not happen anymore.
