Title: data matrix file loader improved a bit

When I tried to load E-MTAB-25 from AE2 through processed data file I found that in the corresponding netCDF file the most part of DEacc array contains "" strings. Unfortunately there were no any warnings or errors in the log and I spent a day to find out what was wrong.

The problem was solved by fixing the processed data file. However I improved the loader code a bit: now it throws an error if design element accession is empty string.
