QCache: Fix crash observed in tst_QAccessibility
Fixes a use-after-free which can reliably be observed under ASAN. In
QConfFileSettingsPrivate::~QConfFileSettingsPrivate we call
unusedCache->insert(conf_file->name, conf_file, ...)
Note that the key is a member of the object. Thus by deleting the object
before using the key, we dereference a dangling pointer.
Amends f08492c6fd9818c7d80b1725355453e179b4d85b.
