Update prettier version and fix formatting bug.

Prettier currently has a bug that causes it's formatWithCursor() to be extremely slow in some cases. In Heynote, whenever you pasted a large JSON chunk and auto formatted it, with the cursor at the beginning or the start of the block, this would trigger that bug. This commit introduces a work around by using format() if the cursor is at the beginning or the end of the block.

Update to latest version of Prettier.
