DBTable's where condition doesn't work when there are multiple condition params

[jakipatryk]

Describe the bug

DBTable#where doesn't work when the argument NamedParams contains more than one param.

To Reproduce

table(tableName)
  .where(add("domain_id", domainID).add("major_version", domainMajorVersion))

where domain_id is UUID and major_version is Integer. This results in ERROR: operator does not exist: integer = uuid.

Expected behavior

It should not fail.
