Library changes behaviour of property decorator

[PFight]

In standard compiler implementation, return value of the property decorator is used for call of Object.defineProperty. See example in on plunker.

If we include reflec-metada library, return value of the property decorator is ingnored. For example, if we include library in previus plunk, it will break.

@PFight Can you npm install reflect-metadata@next to see if this change addresses your issue?

[PFight]

@rbuckton yes, in v0.1.9 it is work good.
