[4.0] Sample data fix - Tags ids need to be sent as a string to the helper

[wilsonge]

Tags need to be submitted as a string to the model rather than as an integer. So simply mapping them to a string here. To test install sample data. Before patch there are integers in the main homepage article tags. After patch they are the expected colours from Joomla 3.

Tested with MySQL 5.7 and PostgreSQL 10.9.

@wilsonge I gave it a good test because it works, but I would prefer if you would also apply my suggested change for using array_slice($tagIds, 0, 3) instead of array($tagIds[0], $tagIds[1], $tagIds[2]).
