Subject: fix(jqLite): traverse `host` property for DocumentFragment in
 inheritedData()

If dealing with a document fragment node with a host element, and no parent, use the host
element as the parent. This enables directives within a Shadow DOM or polyfilled Shadow DOM
to lookup parent controllers.

Closes #6637
