[Bug Report] Bad transaction for attachment process

[yamelsenih]

Bug report

The process Setup Storage for Files System when the attachments are exported it is not taking the transaction created for each attachment, instead it takes the one from the process.

int attachmentReferenceId = DB.getSQLValue(get_TrxName(), "SELECT AD_AttachmentReference_ID "
											+ "FROM AD_AttachmentReference "
											+ "WHERE AD_Attachment_ID = ? "
											+ "AND FileName = ? "
											+ "AND FileHandler_ID = ?", attachmentPair.getKey(), entry.getName(), getAppSupportId());
									if(attachmentReferenceId < 0) {
										try {
											AttachmentUtil.getInstance(getCtx())
												.withData(entry.getData())
												.withAttachmentId(attachmentPair.getKey())
												.withFileName(entry.getName())
												.withDescription(Msg.getMsg(getCtx(), "CreatedFromSetupExternalStorage"))
												.withFileHandlerId(getFileHandlerId())
												.saveAttachment();
											addLog(entry.getName() + ": @Ok@");
											processed.incrementAndGet();
										} catch (Exception e) {
											log.warning("Error: " + e.getLocalizedMessage());
											addLog("@ErrorProcessingFile@ " + entry.getName() + ": " + e.getLocalizedMessage());
											errors.incrementAndGet();
										}
									} else {
										addLog(entry.getName() + ": @Ignored@");
										ignored.incrementAndGet();
									}
								}

The follow code snipet will should use the var trxName instead methos get_TrxName()

int attachmentReferenceId = DB.getSQLValue(get_TrxName(), 

Steps to reproduce

1. Go to System Admin -> General Rules -> Setup Storage for Files System
2. Run process
