core: DB upgrade from 3.0 to 3.1 fails(#880350)

upgrade from 3.0.x to 3.1 failed in 2 points ;

1) 03_01_0950

Reason : script assumes that a storage is in only one DC and attempt to
insert duplicate rows that violates primary key to the permission table

Solution: check before inserting to permissions table that record with
the same key does not exist

2) 03_01_1020

Reason :script adds a column_id column to the async_tasks table.
Since this column type is UUID and is defined as NOT NULL, the addition
will fail if at the point that this upgrade script is running the table
is not empty

Solution : Create the column with an empty UUID (00000.....000000)
DEFAULT
After this column was added , drop the default.
