Run _init_credential_provider before executing deserialized logical plan if credential_provider="auto"

[nameexhaustion]

Description

This currently doesn't run and instead the credentials from the system that serialized the plan is used instead (or no provider is used, if no credential provider ends up getting serialized). This can break e.g. if a query plan is created on a local system that has differing credentials from the remote system that actually executes the plan.
