<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Tests: Do whitespace replacement in `assertDiscardWhitespace()` only when string.
The `assertDiscardWhitespace()` method uses `assertEquals()` under the hood, meaning that in reality any type of actual/expected value should be accepted by the function. Fixed the documentation to reflect that.
At the same time, only strings can contain whitespace differences. So the whitespace replacement should only be done when string values are passed.
This change (a) prevents potential `passing null to non-nullable` errors on PHP 8.1, if either of the inputs would turn out to be `null` and (b) increases tests stability.
