Fixes #2176 Data importer: error when "Reload under the same settings"

[rwmcintosh]

Fixes #2176

Description

A calculation is made to determine if data sets are equivalent or not, one of the checks is to make sure that all the metadata is the same. In the case from the issue the metadata are different in that there is additional metadata in the new import rather than just different values. That was not taken into account
