bitbake: toaster: refactor build model

We remove the "timespent", "errors_no" and "warnings_no" fields
in favor of computing the needed values at runtime. This prevents
inconsistencies in the UI.

Also removeing all references to BuildRequests from the interface -
all build details now display in the build dashboard.

Minor fixes related to data logging.
