Resume original session even if any of the pending sessions fail

Regardless of the result of the pending session, we resume installation
if DIS calls onAllDependciesResolved. This is to avoid edge cases, such
as, a pending session failng becuase the dependency already got
installed somehow else. There is no harm in trying to install. The
original sesson will fail if any dependencies remain missing.

We still fail the original session immediately if
onFailureToResolveAllDependencies.
