g:lastplace_open_folds doesn't work when foldmethod is set in modeline

[djpohly]

Since the BufRead event happens before modelines are processed, lastplace cannot tell when the cursor will be inside a fold. It sounds from :help BufRead that BufWinEnter would be the right place for this functionality.

@djpohly could you test and see if this bug has been fixed? i don't use folds very much, but i think i've found and fixed the issue you found. Thanks for the bug report and your help!
