bitbake: toaster: refactor checksettings command

This patch refactors the checksetting command to prevent
early return from the handle function.

It also adds a check that marks IN PROGRESS builds at startup time
as FAILED. Minor changes to BuildRequest and Build classes
ensure useful string representation for the objects.
