BIT-273: Rename old unit tests to follow standard

[KatherineInCode]

🎟️ Tracking

BIT-273 - Rename all of the unit tests in Networking to follow our new unit test naming scheme

🚧 Type of change

• 🧹 Tech debt (refactoring, code cleanup, dependency upgrades, etc.)

📔 Objective

Various unit tests were named with camel case (testInit), while the standard in the codebase is underscores between camel case components (test_init). This unifies all the old tests to that new standard

⏰ Reminders before review

• Contributor guidelines followed
• All formatters and local linters executed and passed
• Written new unit and / or integration tests where applicable
• Used internationalization (i18n) for all UI strings
• CI builds passed
• Communicated to DevOps any deployment requirements
• Updated any necessary documentation or informed the documentation team
