[TASK] Create a script that will populate DB entries with their assetid for older items

[Mario-SO]

Description

As found in this issue (#853) there is a problem with older entries in the database when we were not saving the assetId returned from livepeer, this caused older videos like ones from Zuzalu to not be playable.

The idea is to populate the database entries that have no assetId by creating a one-of script that based on other fields, could return the assetId so that we can simplify the logic applied when fetching videoUrl for playback.
