[BUG] Loading connection to Integration connected after SDK client is created doesn't work

[Vikram Sreekanti]

Describe the bug
Because we retrieve the integrations list when we create the client, a user can't connect to an integration they create after creating a client, which is cumbersome. If the integration the user specified isn't in the list we have locally, we should update our list with what's on the server.

To Reproduce

• Create an SDK client
• Connect a new integration from the UI
• Attempt to load a connection to the integration from the previously-created SDK client

Expected behavior
We should reload the list of integrations when the user attempts to connect one, so we don't run into this inconsistency.
