Reflection: fix exceptions on concurrent access to some properties

Browse Source 
Using `ReflectionProperties.lazy` is incorrect because it allows several
threads to observe different resulting values if they're computing it
simultaneously (unlike `lazy(PUBLICATION)`, which always returns the
value that "won the race").

In the case of property delegates, for example, if we're invoking
`isAccessible = true` and then `getDelegate()` concurrently, it might
happen that when some thread invokes `getDelegate()`, it gets the
underlying Field object which was written by another thread and which
has not yet been made accessible, leading to
IllegalPropertyDelegateAccessException.
