useDocked does not work on older OpenFin versions

[ms14981]

Tested on OpenFin version 9.61.31.76 (see https://developer.openfin.co/versions/?product=Runtime&version=9.61.31.76).

The issue seems to be that the version of the npm package openfin-layouts is not compatible, and causes the whole demo app to crash on launch if the package is in the package.json dependencies.

This issue is not the case from version 9.61.38.43 (see https://developer.openfin.co/versions/?product=Runtime&version=9.61.38.43) and perhaps earlier.
