Title: [STORE] Improve exception from Store.failIfCorrupted

If you have previously corrupted files, this method currently builds an
exception like:
```
failed engine [corrupted preexisting index]
failed to start shard
```

Followed by a CorruptIndexException. This commit writes the entire
stacktrace to provide additional information. It also changes the
failure message from `corrupted preexisting index` to `preexisting
corrupted index` to prevent confusion.

Closes #7596
