   This bug only occurs in IoTDB 0.11.
   When querying Last value from an empty timeseries, the server gives an 
exception and no result output.
   
   To Reproduce:
   1. Create a new timeseries
   ```
   CREATE TIMESERIES root.sg.d1.temperature WITH DATATYPE=FLOAT, ENCODING=RLE
   ```
   2. Query last value of this timeseries
   ```
   select last temperature from root.sg.d1
   ```
