Mute single mode output when there is no words to work with #5945
Description
See #5944 (comment)
When there's no login, gecos nor any other info for seed words, we could want to mute the 'single' mode output for improving signal-to-noise ratio in the output:
Proceeding with single, rules:Single
Almost done: Processing the remaining buffered candidate passwords, if any.
We could opt to still output something along the lines of "Single mode skipped for lack of seed words" but then we're down to very small reduction of output (though more accurate info).
