Fix a couple small bugs in the new pc-updategui:
1) Make sure the UI is properly updated after loading all the initial updates so the summary labels are showing the proper text.
2) Remove the "syscache not running" error and instead have it assume that an update is running (active detect the reboot flag as well). This allows the user to still use the utility for viewing the log file while an update is running.
