issue warning when calling polymerCreated twice #371

Originally opened as dart-lang/sdk#15360
Common error:
- extend DivElement, use 'polymerCreated' explicitly
- switch to extend PolymerElement, but forgot to remove the 'polymerCreated' call.
- problem: polymerCreated is invoked twice
Possible solutions:
- provide warnings in the linter: this is unfortunately something we can't do without full use of the dart analyzer/resoltion, which can be expensive
- make polymerCreated reentrant (at least print a warning the second time it's invoked).
