Don't use QSettings to "cache" plugin information
The main rationale of the cache was to examine the plugin's build-key
before loading it. Now that the build-key has been removed, the cache
has lost its usefulness.
This is part of a larger push to not use QSettings for Qt specific
settings or caches.

Right before the unloading happen, the root component will also be deleted. - In order to speed up loading and validation of plugins, some of - the information that is collected during loading is cached in - persistent memory (through QSettings).
