Fix issue where spark-tests was producing an unintended error code

[abellina]

There was an issue in spark-tests.sh that caused builds to fail, and it is due to a shell expression that conditionally executes using &&. This can produce an error code, demonstrated by this sample:

[[ "bananas" = "apples" ]] && echo "error code set"
echo $?

if [[ "bananas" = "apples" ]]; then
  echo "bad"
fi
echo $?

if [[ "apples" = "apples" ]]; then
  echo "good"
fi
echo $?

This will print 1, 0, 0. Since the script had -e set, the error code is fatal and aborts the job. One solution is to make it an if statement.
