Screenshots and page source saved erroneously with save_screenshot_on_failure and save_page_source_on_failure even on success

[PyGenych]

Preconditions:

1. Version: 2.0.0rc9
2. browser.config.save_screenshot_on_failure is True
3. browser.config.save_page_source_on_failure is True

Steps:

1. Ensure that browser.wait_until() function returns False
   Example:

from selene import browser
browser.wait_until(False)

But the program completed successfully without unhandled exceptions.

2. Check selene folder in your system (for example on Ubuntu its /home/<username>/.selene/screenshots by default)

Actual result:
Added a screenshots folder to the selene folder with two files: png-screenshot and html-page-source.

Expected result:
The screenshots folder should not be added to the selene folder since all exceptions have been handled.

Additional info:
Screenshot and page source should only be taken if the program terminated with an unhandled exception.
