Update RebuildComponent.h

Quickbuilds jump fix

Corrected an error where the builder was erronously changed to an empty lwoobjid when a quickbuild was completed, causing the builds to no longer jump on completion (if configured to do so.)  Packet captures from live show that we do not want to get rid of the builder during resetting or during completion of the build so the file has been changed to not clear the builder in those cases.
