chore(wdio): migrate slot-no-default to wdio

port the `test/karma/test-app/slot-no-default` test suite to webdriverio

git history has been preserved as much as possible here, using `git mv`
to move files from the `karma` dir to `wdio/` in all possible cases.
however, git may fail to mark some files as 'moved' if we change a file
enough that it exceeds git's "sameness threshold".
