Mass Privater: Display total fetched count without filtering

[marcustyphoon]

Description

Resolves #1609.

This changes the "checked x" count that Mass Privater shows while fetching posts to include all posts without any filtering, ensuring that it continues to increment in real time even if the posts currently being fetched aren't relevant.

This includes counting the same post multiple times if it has multiple searched tags and gets fetched multiple times; do you think this makes sense? (Maybe it makes "checked x" slightly inaccurate; that could be "fetched x" or "downloaded x" something, I dunno.) There's a tradeoff here.

Testing steps

I did not really test this, as I don't have enough private posts to notice the difference.

After much thought, I'm concluding that I don't care. It's probably a rare enough scenario that it's not worth the mental effort to accommodate writing 100% accurate copy for.

Works. Easily tested on a blog with only 22 posts, 20 of which were private.
