function Constraint::toStringInContext

Returns a custom string representation of the constraint object when it appears in context of an $operator expression.

The purpose of this method is to provide meaningful descriptive string in context of operators such as LogicalNot. Native PHPUnit constraints are supported out of the box by LogicalNot, but externally developed ones had no way to provide correct strings in this context.

The method shall return empty string, when it does not handle customization by itself.
