> Starting from 1.10.0 `PropertyValue::isExpressionLanguagePresent` seems to
> always return true on non-null values.
> Query parser treats property value as a string literal expression, adds it to
> expression list on a query object, and, since expressions list is not empty,
> the property is considered as having expression language.
> Seems to be introduced by this commit
