`convert_test`: Delete obsolete condition around ASSERT_EQ in TestWithMultipleFormatsHelper

The `if (actual != expected)` makes the `ASSERT_EQ(actual, expected)` trigger only when the assertion fails. However, a successful `ASSERT_EQ` takes a negligible amount of time, which means the `if` is useless and only makes the test harder to read.
