Add public way to clear subscribers?

[matthewmcgarvey]

I'm working on wrapping specs in transactions. I'm using a Pulsar event to run code whenever a new database connection is created. The problem is that there are situations where I would like to be able to clear all the subscribers:

• I'll be calling subscribe for every spec and I don't want multiple subscribers so I clear afterwards
• In situations where I don't want to do the transaction code, I want to clear the subscriber if it exists

Would it make sense to add a public Pulsar::Event.clear to clear any subscribers? Don't know if that's a good name for it (I used clear_subscribers in my code)

Reference: luckyframework/avram#780

I think I needed to do that too at one point, but I forget why. I like clear_subscribers, it reads well.
