[Testing]: add more coverage for update.ts

[jsjoeio]

For #TestingMondays, I'd like to increase our coverage for src/node/update.ts. These lines are missing coverage:

• 111-112
• 116-124

We should be able to do this by adding a couple more test cases and overriding the provider along with adding a couple new test endpoints in the suite setup. See this as an example.
