Description
Related to #3211
e.g. if __construct calls $this->_init(), and _init sets the value of $this->prop, then either clear the known types for the property or set types to the new type (if nearly certain that that will be the new value).

Research direction
Start by reading related issue #3211 and tracing how Phan tracks known types for properties of $this across method calls. Check the handling of __construct calling _init and determine the evidence needed to clear or update the property's known type; done when the intended invalidation or inference behavior is covered for this case.
