Agnik47 3d1980560e fix(cartesia,pipecat): fall through to chunk when memory is empty
`_field` returns the first value that is not None. A v4 hybrid-search hit
shaped `{"memory": "", "chunk": "..."}` therefore resolves to the empty
string and never falls through to `chunk` — the exact fallback the call
site's comment says it is there for.

The consequences are in both directions. In `deduplicate_memories` the hit
produces an empty comparison key and is dropped, so the memory never reaches
the prompt. When such an item does survive, `format_memories_to_text` renders
it through the same `_field` call and emits a bare `- [16 hrs ago] `.

The TypeScript `getMemoryText` takes the first non-empty field instead, and
`agent-framework-python` and `openai-sdk-python` both already match it; the
two voice SDKs were the only implementations that disagreed. Add a
`_memory_text` helper mirroring the TypeScript semantics and use it on both
the dedup and the render path.

Also add tests/conftest.py to pipecat so the import stubs are installed
regardless of collection order — test_utils.py cannot import the package
on its own otherwise.
