Fix segfaults when failing to fetch compressed repositories

The ComponentModel object was not always reset in case we already got
to the point of clearing the source data (deleted components owned by
PackageManagerCore from previous fetch) and failed after that, leaving
the model with dangling pointers to the deleted component objects.

If we were already on ComponentSelectionPage, this would cause
segmentation faults when the component tree view using the model would
be shown again after fetch.
