[Zeppelin-1555] Eliminate prefix in PythonInterpreter exception

### What is this PR for?
Solve bug metioned 
[here](https://github.com/apache/zeppelin/blob/3dec4d7006b8a57136f34ae330ba937d8990f2d2/python/src/main/java/org/apache/zeppelin/python/PythonInterpreter.java#L139)

Since we launch python interpreter as a process and redirect stdin and 
stdout, only exception occurred (like syntax error or indentation error, etc) 
could give string like `...`. Thus, we don't need to determine whether syntax 
error happened in 
[`PythonProcess.sendAndGetResult`](https://github.com/apache/zeppelin/blob/3dec4d7006b8a57136f34ae330ba937d8990f2d2/python/src/main/java/org/apache/zeppelin/python/PythonProcess.java#L86)
 because we have detected error in 
[`PythonInterpreter.pythonErrorIn`](https://github.com/apache/zeppelin/blob/3dec4d7006b8a57136f34ae330ba937d8990f2d2/python/src/main/java/org/apache/zeppelin/python/PythonInterpreter.java#L152)
