Prevent `RangeError` for `FinderMethods#exists?`

`FinderMethods#exists?` should return a boolean rather than raising an
exception.

`UniquenessValidator#build_relation` catches a `RangeError` because it
includes type casting due to a string value truncation. But a string
value truncation was removed at #23523 then type casting in
`build_relation` is no longer necessary. aa06231 removes type casting in
`build_relation` then a `RangeError` moves to `relation.exists?`.

This change will remove the catching a `RangeError`.
