Change text of the information regarding failed analysis when there are more than one dataCollection metadata field group

[wfenrich]

Currently we say:

[genericAbortedStepInformation]. Dataset version should have exactly one dataCollection field. Current version has: [numberOfGroups].

Should be:

[genericAbortedStepInformation]. Analysis is possible only for dataset versions having exactly one "Data Collection" metadata group, while this version has [numberOfGroups].
