CSV line scanner skipping final line when last column is empty in 1.0.1

[RoccoMathijn]

With version 1.0.1 of Alpakka CSV the line scanner skips the final line when the last line does not have a line ending and the last column in this line is empty.

I've recreated the issue using the demo app from kciesielski from this slightly related issue: #315

With 1.0.0 both of the tests succeed. With 1.0.1 the last one fails.

edit: I simplified some things in the issue. First I thought the problem only occurred when the last line had a column less than the rest AND the last column was empty. But the number of columns doesn't seem to matter.

Thank you for reporting, this must have been introduced by the optimisations in #1685.

Fixed with #1711
