ROU-12857: Ensure directions waypoints are always defined

[os-davidlourenco]

This PR is to improve the directions waypoints instantiation to ensure it is never undefined.

What was happening

• When the user tried to remove routes without adding them first, the waypoints array was undefined
• The access to the waypoint length when the waypoints were undefined raised an error

What was done

• In the instantiation of the waypoint, an empty array is used the value is undefined

Test Steps

1. Open the sample application
2. Open the development tools
3. Validate that no error is visible on the console

Checklist

• tested locally
• documented the code
• clean all warnings and errors of eslint
• requires changes in OutSystems (if so, provide a module with changes)
• requires new sample page in OutSystems (if so, provide a module with changes)
