bitbake: toasterui: disable autocommit for build logging

This patch disables autocommit for inserting build data,
effectively updating all build data in a single transaction.

This is a purely performance improvement patch, as the transaction
will always be commited.

Similar manual transaction handling in the layer source update
method. Added feedback messages during update method.
