We currently report description field for numbers. On client side user
can calculate description as remoteObject.unserializableValue ||
(remoteObject.value + ''). Let's report description only for objects to
simplify value -> remoteObject logic a bit.

This refactoring makes it easier to write advanced tests and
gives full control over what's happening to the test code.
It also forces description for every test.

With this CL we don't need to store reference to InspectedContext inside of JavaScript console object and able to get all required information from callback data.
It allows us to implement console methods without taking in account how and where we create and store these methods:
- later we can move console object implementation to builtins..
- ..and install command line API methods smarter.

- added InspectorTest.setupInjectedScriptEnvironment method which mutates current context,
- clear prototype of InjectedScript function and domAttributesWithObservableSideEffectOnGet.

Second point increases chances that injected-script-source would be successfully compiled.
