Eliminate false positives in Checking data consistency

[alexfoias]

This is due to the fact that the script is checking all git annex files *.nii.gz

Same for spine-generic/data-multi-subject#67

@alexfoias can you please elaborate what you mean by "false positives"? Can you maybe give an example?

When running CI on the current dataset, Checking data consistency section yields false positive Missing jsonSidecar for the .nii.gz files that are located in git-annex. We don't have to check the jsonSidecar files for git-annex files.
