Enriching the metadata with the process title is not supported in mass import

[BartChris]

Is your feature request related to a problem? Please describe.
There is a feature which allows to enrich metadata fields with the process title. It was implemented in the following PR: #5623
This does however not work during mass import as the required logic only gets called in the case of a normal process creation, when saveProcessHierarchyMetadata is called:

kitodo-production/Kitodo/src/main/java/org/kitodo/production/forms/createprocess/CreateProcessForm.java

Lines 622 to 634 in 9d7b4b8

	private void saveProcessHierarchyMetadata() {
	// save ancestor processes meta.xml files
	for (TempProcess tempProcess : this.processes) {
	if (this.processes.indexOf(tempProcess) == 0) {
	tempProcess.getProcessMetadata().preserve();
	}
	saveTempProcessMetadata(tempProcess);
	}
	// save child processes meta.xml files
	for (TempProcess tempProcess : this.childProcesses) {
	saveTempProcessMetadata(tempProcess);
	}
	}

Describe the solution you'd like
After the problems with the current enrichment of metadata with the process title (see: #6024) are solved, this feature should also be usable in case of a mass import.
