lib-index: Assert-crashfix on some rare situations. mail_index_modseq_get_next_log_offset() might have returned e.g. (seq=4, offset=40) to point to the beginning of a next file. The view itself could still have been pointing to seq=3 end of file. Now calling mail_transaction_log_view_set() with these two positions (that are basically the same) should result in an empty view instead of assert crash.
