Fixed SafeEventEmitterProvider invalid default params (#4603)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
The SafeEventEmitterProvider is failing to send net_version requests
correctly because it's using an empty object as the default params when
none are provided.

While some methods do use an object for params, the vast majority use an
array instead. Passing an empty object as the params for a method that
has array parameters can result in failure (as is the case for
net_version).
