Removes label from previous list

Closes #28484

See merge request !9418

Moved the issue boards card template into the JS. This helps to improve
the code coverage & will eventually make it easier to move this to .vue
files

When dragging an issue to a list that it already exists in it was previously not removing the label for the list it was moving from. This changes that to make that API call.
