extract_tables() only does first few pages

[jzadra]

I have a 400+ page pdf. When I use extract_tables() without specifying the pages, it only returns the first page. I had a blank second page, so I deleted it and tried again without specifying the pages, and I got back 3 tables this time, from the first and second pages.

When I specify any of the 400 pages specifically, I get tables for that page. When I give the pages argument a vector of 1:400, I get the same result as leaving it blank (just the first few pages).
