Description

Create table if not exists has following problems if run concurrently from different drivers 

1) Sometimes It fails with error "Table <db.table> already exists." 
2) Create table failed driver still holds the table with wrong path or schema. Eventual operations refer the wrong path
3) Stale path created during create table is not deleted for ever [After 1.5.0 version table will be created in a new folder using UUID if folder with table name already exists]
