Data-Release -: Issue with EBI Search Index file generation

[sajo-ebi]

There was an issue in Python script where we got the following error -:

[INFO] Database connection to SPOTREL was successful
[Warning] Number of studies do not match.
Traceback (most recent call last):

Changed Python script in conda package path to handle Name error , will make code changes to the repo https://github.com/EBISPOT/gwas-ebi-search-index , @karatugo to investigate why the script doesn't work with gwas-utils conda package but only works with gwas-utils-dev conda package
