[SPARK-14783] Preserve full exception stacktrace in IsolatedClientLoader
In IsolatedClientLoader, we have a`catch` block which throws an exception
without wrapping the original exception, causing the full exception stacktrace
and any nested exceptions to be lost. This patch fixes this, improving the
usefulness of classloading error messages.
