Test --no-decim

We saw a bug where renamed streams had missing data at the end.  I
think what happened is:

- Write data to /old/path
- Rename to /new/path
- Write data to /new/path
- Cache entry for /old/path gets evicted, file gets truncated

Instead, make sure we evict /old/path right away when renaming.
