Trix: Bug: additional <br> is created if the value ends with <br>

[antpaw]

in this example one additional <br> is created at the end of the value
https://jsfiddle.net/antpaw/r6bvoqyL/

in this example no additional <br> is created at the end of the value
https://jsfiddle.net/antpaw/tcqacact/

I think it should be consistent and I like the way second example works better.

[antpaw]

the last example was wrong, this is the example that doesn't create an additional
because it ends with a letter.
