fix: Fix TransferOut test

[dadepo]

Closes #1276

Description

Fixed the TransferOut receipt test

Changelog

The core of the change:

• Updated the contract to use transfer_to_address
• Updated the address the contract transfers too
• Appended append_variable_outputs when calling the contract methods

PS. The tests passes locally except for commands::test_fuel_indexer_api_server_help_output and commands::test_fuel_indexer_api_server_run_help_output but then they were also failing for me locally on develop branch.

@dadepo Thanks for working on this, looks like everything works! Before approval, would you mind re-integrating the TransferOut test at the bottom of the index_receipt_types test? We had originally split it out to be able to ignore it, and now that you've fixed it, we can place it back where it belongs. 😄
