lib: fix guard expression in timer.unref() Fixes the following assertion on slow systems, like our ARM buildbot: $ out/Debug/node test/simple/test-timers-unref.js node: ../src/async-wrap-inl.h:101: v8::Handle<v8::Value> node::AsyncWrap::MakeCallback(uint32_t, int, v8::Handle<v8::Value>*): Assertion `cb_v->IsFunction()' failed. Aborted The reason it only manifests on slow systems is that the test starts a 1 ms interval timer, then defers timer.unref.bind({}) to the next tick. On fast systems, the test completes in under a millisecond, before the callback is called. This commit makes timer.unref() check that the receiver actually has a timeout callback property. Fixes #13.
