The -k option will be deprecated. Please use the --set-key-file option
instead.
This isn't causing any problems _yet_, but it seems easy enough to fix it now
already.
There now is a "Refresh Hardware Keys" icon since 2.7.7, which we have to skip.
I also needed to add more explicit handling of the intermediate file dialog to
get the test to pass.
The test was failing because it was timing out. Turns out it was waiting
for `foo.kdbx`, which couldn't be "seen" even if it actually existed
(probably some contrast issues with the theme and OCR couldn't find it).
Fixed it by delegating the check to the next screen, where the full path
to the file is displayed in a bigger size. The test seems to pass.
