Send back single formatted TextEdit

[bmulvihill]

Fixes #35

• Formats document with a single TextEdit rather than many since we end up formatting the entire source anyway

@bmulvihill Thanks you!

This bug is my fault 😅

I tried to fix a bug, related to files above 10000 characters, I thought this was because I was using a single TextEdit, so I implemented multiples Textedit ¹ Then I found I was using content.size instead of content.bytesize ² but my bad implementation kept in codebase 😅

   # NOTE: Some clients don't support newText bigger that 10000 characters.
