Regression for unsigned column changes

[spand]

It seems that since #1799 it is no longer possible to have multiple tables with unsigned columns since check constraints are not scoped to a table but in a global namespace.

I have created a failing test case that fails with following exception:

org.jetbrains.exposed.exceptions.ExposedSQLException: org.h2.jdbc.JdbcSQLSyntaxErrorException: Constraint "CHK_UNSIGNED_USHORT" already exists; SQL statement:
CREATE TABLE IF NOT EXISTS USHORT_TABLE2 (USHORT INT NOT NULL, CONSTRAINT chk_unsigned_ushort CHECK (USHORT BETWEEN 0 AND 65535)) [90045-220]
SQL: [CREATE TABLE IF NOT EXISTS USHORT_TABLE2 (USHORT INT NOT NULL, CONSTRAINT chk_unsigned_ushort CHECK (USHORT BETWEEN 0 AND 65535))]

My mistake. I see that it has already been reported in Youtrack.
