test(table): update tests for updateData with targeted reformat

- Expect updateData (not replaceData) for row content changes
- Assert pool.releaseAll is not called for content-only changes
- Add test for fillMissingFields patching dropped fields as undefined
- Mock updateData to return a Promise and getRow to return reformat
