Remove usage of anti-pattern getBeansOfType

Earle mentioned on SAK-42394 that usage of getting the beans during init and injecting them was an anti-pattern and should be removed. 

If it can't be done using dependencies (as Matt already stated) then by design I would potentially look at removing the use of:
applicationContext.getBeansOfType(LearningResourceStoreProvider.class, true, false);
by having the providers perform their own registration with service via org.sakaiproject.event.impl.BaseLearningResourceStoreService#registerProvider vs the service attempting to do it for them.

I looked and there were 4 places doing this in core that should be investigated to see if we can remove these. Contrib tools that make use of this pattern would break but we should be able to fix these for core. Everything now except the one in basiclti are calling with the third parameter as "false".
