MIG-171 - Fixed ECBuilderMap and script

[imaimai86]

Fixed ECBuilderMap and script to update only ids in ec_builder_data and export only draft templates in the target org

Changes in export:

• Fixed the Ec builder data map to contain only ids and ec_keys
• Export Builder data maps for affected templates only(those being exported)
• Export Builder data maps for published templates as well, if they are being exported

Changes in import:

• Update only the ids of the ec__builder_data in target org
• Update template in the target org only if they are in draft status

Common:

• Fixed tests

Quick question @imaimai86, do you think the existing tests you have modified are cover all of the scenarios of the changes or do we need to add some more tests?

@joejean The tests in the repo covers export part of the process, and the modified tests covers the changes we made to the export
