plt/racket — Issue #61: sequence-filter fails if the resulting sequence is empty

Code snippet demonstrating the issue:

(sequence-length (sequence-filter (thunk* #t) empty-sequence))

Line 123 of sequence.rkt reads:
```scheme
(if (apply f vals)
```
I believe it should read:
```scheme
(if (or (not vals)
(apply f vals))
```
to mimic lines 128-129
