Fixed bug #78774

Browse source 
The string held by the zend_type may be released if the property
type gets resolved to a CE. I initially wanted to fix this by
storing a zend_type* instead (so the property type resolution
propagates to the ReflectionType), but decided against this in
light of upcoming union types support, where we also need to
represent parts of the union, and will not have a single zend_type*
we can reference.
