The test "assertThrows(builder.instantiate)" threw a TypeError before,
which made the test pass, but not because of the feature we wanted to
test.
This CL fixes the test to call builder.instantiate correctly, and also
tests for the correct error message.
Drive-by fix: Fix {expected} and {found} parameters in assertThrows.
