	[Bug #19985] Raise LoadError with the converted feature name

	`Kernel#require` converts feature name objects that have the `to_path`
	method such as `Pathname`, but had used the original object on error
	and had resulted in an unexpected `TypeError`.

	Ease the `Encoding::CompatibilityError` test failure

	At the time this test first started using `assert_raise_with_message`,
	it did not touch `Encoding.default_internal`.
