Incorrect line wrapping for tasks with long descriptions

[jonhoo]

To reproduce:

1. Define a task whose description is long enough to wrap in your terminal.
2. Make your terminal fairly narrow.
3. Run kraken q ls.
4. Notice that the wrapped lines of the description (that is, every line except the first for each task) is wrapped very narrowly.

This happens because we use the subsequent_ident argument to textwrap.wrap:

https://github.com/kraken-build/kraken-build/blob/fcb55055a56ec703729315b462820cfd363c26bb/kraken-core/src/kraken/core/cli/main.py#L324-L328

And subsequent_indent counts towards the line length of each line except the first. In other words, if the terminal is 120 wide and remaining_width = 60, we'll end up passing 120-60 space characters to subsequent_lines, and those will be counted against the remaining_width we pass as the width argument. Which effectively means there is zero remaining space, and so textwrap dutifully wraps the remaining lines as aggressively as it can.

The solution here is probably to not pass subsequent_indent, and instead just prepend the spaces onto each line (except the first) that textwrap.wrap returns.
