[CARBONDATA-3119] Fixing the getOrCreateCarbonSession method parameter to an empty string

Fixing the getOrCreateCarbonSession method parameter to an empty string causes the select table data to be empty

problem: When create carbonSession in this way: [val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("")],The prompt can be created successfully, with no exceptions thrown during the process, but ultimately [carbon.sql("SELECT * FROM TABLE").show()] is empty.

cause: [carbon.sql("SELECT * FROM TABLE").show()] is empty.

solution: Increases the null or empty judgment of getOrCreateCarbonSession method  parameters[storePath,metaStorePath]

This closes #2961
