Tech debt: avoid caching with some test context properties (#3379)

## Changes

This PR modifies some properties on the integration test context so that
they don't cache their return values; these properties are based on
internal mutable state and the current caching situation makes it
difficult to know if they are yielding the current value or an earlier
one that might no longer be correct.

### Tests
