Some dummy content CSV files cause errors

[thierrydallacroce]

Steps to reproduce:

1. dktl install (from master)
2. dktl drush dkan-dummy-content:create
3. dktl drush cron
4. dktl drush dkan-datastore:list
5. dktl drush dkan-harvest:list

Will output errors such as:

[error]  Import for 144f86b3-9828-556a-be7c-9331b9843dc3 returned an error: Machine did not halt

)

I diagnosed the issues to the following dummy content CSV files:

1. docroot/profiles/contrib/dkan2/modules/custom/dkan_dummy_content/files/district_centerpoints_0.csv has right-to-left characters
2. docroot/profiles/contrib/dkan2/modules/custom/dkan_dummy_content/files/data_0.csv has Windows line endings
