toaster: display Toaster exceptions and other fixes

Changing ToasterUI to log toaster exceptions on a different level than
build errors.

Updating the build dashboard to show Toaster exceptions.

We add extra logging to console for exceptions.

Fixed a problem where packages database entries were created instead of
being looked up in the database, conficting with entries created to
satisfy dependency information.

Toaster now checks for invalid states at startup and performs needed
cleanups.

Removed loading reference to jquery-ui.min.css as we do not have this
file.
