Don't trim whitespace in input text needlessly

[Caesarovich]

This PR disables text trimming where it is unneeded. It comes in response to #62

At line 233 there was this line of code:

let contentWidth = widestLine(wrapAnsi(text, columns - BORDERS_WIDTH, {hard: true})) + padding.left + padding.right;

This line has for goal to determine the columns that the text would take with the padding.
The problem is that by default the wrapAnsi function trims the lines, hence removing the whitespaces in #62 . This is certainly an unwanted behavior because it alters the user input with no reason.
So I added the trim: false option in the wrapAnsi function.

I also needed to adapt my tests because it is not something I realized when making the code refactoring PR.

I think it would make sense to switch some of the tests to snapshot tests. It would be easier to update and easier to see the changes.

What do you mean by that ? Tests that compare results between two versions of the code ?

Oh yeah this is even better, it's really sweet. Do you want me to work on that ?

[sindresorhus]

Sure, if you want.

Ok, working on that for tomorrow ;)
