Stage-deploy does not account for -build.x products

Maybe my stage-deploy task simplification was naive, because now on products that have a *-build.11 semver system, it falls apart.

Healthwatch 1.1.7:

Archive:  ./pivnet-product/p-healthwatch-1.1.7-build.11.pivotal
   creating: metadata/
 extracting: metadata/p_healthwatch.yml  
could not execute "stage-product": failed to stage product: cannot find product p-healthwatch 1.1.7

It wants to be configured with the "full" version, e.g., 1.1.7-build.11

Added some extra parsing logic to remove single/double quote marks. Not perfect, but for now it will do 👍
