Select only preinstalled Spell Checker Services
When we are setting a new spell checker as the default one in
Secure.Settings, TSMS#findAvailSpellCheckerLocked can pick up
any available spell checker service. This violates the principle
that user should be warned whenever we are setting an untrusted
spell checker service as the default service, since the warning
dialog is never shown.
