Description:

This PR fixes a problem with forkJoin's inspection of its first argument to determine whether or not it should be joining the properties of an object literal.

The current code checks to see if the argument is not an Observable and if it isn't, it proceeds as if it has been called with an object literal. However. the argument could be another ObservableInput - like a Promise.

This PR adds a failing test and changes the check to compare the argument's prototype to Object.prototype.

Related issue (if exists): #4737
