[WIP][SPARK-17902][R] Revive stringsAsFactors option for collect() in SparkR
## What changes were proposed in this pull request?
This PR proposes to revive `stringsAsFactors` option in collect API, which
was mistakenly removed in
https://github.com/apache/spark/commit/71a138cd0e0a14e8426f97877e3b52a562bbd02c.
Simply, it casts `charactor` to `factor` if it meets the condition,
`stringsAsFactors && is.character(vec)` in primitive type conversion.
## How was this patch tested?
Unit test in `R/pkg/tests/fulltests/test_sparkSQL.R`.
