get() method's switch to object.prototype.propertyIsEnumerable broke my code #46

This change was made in July 2016:

use `object.prototype.propertyIsEnumerable instead of `Object.getOwnPropertyDescriptor`

Unfortunately, this change broke my code. Specifically, I was using it like this in the Express framework:

dot = require( "dot-prop" );
req.app.locals.foo = 1;
console.log( "foo = " + dot.get( req, "app.locals.foo" ) );

where the req object is defined here.

Before this change, foo = 1 was logged. After this change, foo = undefined was logged.

The problem appears to be that req.app isn't an enumerable property because it is an inherited property.

So, here's my question: why are we discriminating against inherited properties inside the get() method? That doesn't seem right to me.
