test(proto): Stop driving the connection before a path idle timer fires (#557)

## Description

This is more in line with what `is_idle` is doing with `ConnIdle` as
well, and in the future once we handle #518 this is even more important,
as the tests expect that calling `pair.drive()` doesn't run the
connection till the idle timeout.

## Breaking Changes

Test changes only.
