[SPARK-19237][SPARKR][CORE] On Windows spark-submit should handle when java is not installed
## What changes were proposed in this pull request?
When SparkR is installed as a R package there might not be any java runtime.
If it is not there SparkR's `sparkR.session()` will block waiting for the connection timeout, hanging the R IDE/shell, without any notification or message.
## How was this patch tested?
manually
- [x] need to test on Windows
