few tweaks to driver finding logic

[titusfortner]

Description

1. Don't execute Java ExecutableFinder() if a System Property has been defined
2. Python log results even if error code isn't 0

Motivation and Context

Ensured logic the same between Java/Python/Ruby/.NET

Does this mean we are letting Selenium Manager find the driver on the PATH in Java?

[titusfortner]

No, not yet. The default parameter for getProperty always evaluates, even when there is a property, which is less performant and unnecessary. So very minor performance improvement; and now we just remove those 3 lines when we do let SM get from PATH.
