Fix URLs getting incorrectly extended to next line

If a URL ends right at the end of the terminal, it would sometimes
incorrectly include the characters from the following line when
launching the URL.

Similar to the semantic search function, the URL parsing iterator will
now stop if it encounters a cell at the end of the line which does not
contain the `WRAPLINE` flag.

This fixes #1906.
