Comment 4 for bug 1752356

Thanks, All. I have pushed a branch with a sign off for Mike's patch, plus an additional commit.

From the commit msg:

Modify wording to clarify the date displayed is that of the block list download and not necessarily the date the patron was flagged expired.

Avoid console errors when the file download date is not known -- edge case where the code is updated but the block list was not updated in the meantime.

Clean up some debug logging.

I also took the liberty of tweaking Mike's commit message to suit community standards (LP number, formatting).
