Sam Brannen f16474d585 Reliably resolve overloaded write methods in PropertyDescriptorUtils
Prior to this commit, the algorithm behind determineBasicProperties()
in PropertyDescriptorUtils did not reliably resolve the correct write
method when one candidate write method had a parameter type that was a
subtype of another candidate write method whose parameter type was an
exact match for the resolved read method's return type.

In other words, the algorithm always resolved the candidate write
method with the most specific parameter type (similar to covariant
return types) which is not necessarily the resolved read method's
return type.

To address that, this commit ensures that determineBasicProperties()
always selects an exact match for the write method whenever possible.

As an added bonus, determineBasicProperties() no longer invokes
BasicPropertyDescriptor.getWriteMethod(), which avoids triggering the
resolution algorithm multiple times (when multiple write method
candidates exist), resulting in lazy resolution of the write method the
first time client code invokes getWriteMethod().
