[CARBONDATA-1509] Fixed bug for maintaining compatibility of decimal type
with older releases of Carbondata
In old Carbondata releases, precision and scale is not stored for decimal
data type and both values are initialized to -1. In TableSpec.ColumnSpec
default values for precision and scale are initialized to 0 because of which
exception is thrown while reading the old store with decimal column. Both
precision and scale should be initialized to -1.
