Currently beam search returns inconsistent outputs - if hypos have different lengths we get eos, if they are the same - we don't.
This PR makes the output consistent.
Also why not also replace:
```
if sent_lengths[i] < max_length:
decoded[i, sent_lengths[i]] = eos_token_id
```
with:
```
decoded[i, sent_lengths[i]] = eos_token_id
```
Shouldn't eos always be there? If the data gets truncated, the caller needs to user a larger `max_length`.
Please correct me if my logic is flawed.
* [gen utils] missing else case
1. `else` is missing - I hit that case while porting a model. Probably needs to assert there?
2. also the comment on top seems to be outdated (just vocab_size is being set there)
