If a `+` is encountered in the middle of parsing a BigUint, this should generate an `ParseIntError::InvalidDigit`. Since we can't create that directly, we get it by trying to parse a `u64` from this point, but of course `+` is a perfectly valid prefix to a `u64`. Now we include the previous character in the string passed to `u64`, so it has proper parsing context to understand what's in error. Fixes rust-num#268.
