Make app installed cert flags persistent

Store AppInstalledRootCaCert and AppInstalledPrivateKey flags
in the config store to make them persistent. Resolves the issue
of certs that remain on the device after a connection is removed.
The reasone was that these flags were not persistent which caused
the logic to treat the certs as installed by the user.
