Jimmy 749b29e599 tests: Don't pretend to be using webkit if unavailable
Since `objects.backend` was being set to usertypes.Backend.QtWebKit by
default some feature detection code was calling
`version.qWebKitVersion()` which was failing because the import of
`PyQt5.QtWebKit` was failing in version.

This should not change behavior where both backends are available on if
any tests fail because they are expecting their environment to say they
are on webkit when they either aren't actually using any webkit features
or all mocked webkit features then they should probably be changed to
patch `objects.backend` or not depend on it.
