[SPARK-14739] [PySpark] Fix bug while parsing all zero sparse vectors
## What changes were proposed in this pull request?
The PySpark deserialization has a bug that shows while deserializing all
zero sparse vectors. This fix filters out empty string tokens before casting,
hence properly stringified SparseVectors successfully get parsed.
## How was this patch tested?
Standard unit-tests similar to other mthods.
(If this patch involves UI changes, please attach a screenshot; otherwise,
