Email addresses in URLs should be extracted

[troyhunt]

Just processing a breach with a bunch of data that looks like this:

That's the output after running the extractor and the problem is that the string "https://example.com/path/test@example.com" is extracting "//example.com/path/test@example.com" as the email address. I think this is another one of those cases where regardless of the spec, a forward slash should be treated as a word break, I just can't think of legitimate cases where there'd be a forward slash in a real email address.

There's now a failing test for this in da5b1f265a4fc6e8437509d92b13a057e29a8de1.

This should be a simple change by removing the / from the Regex ('+/=? to '+=?)
