[Bug] 2 snippets which make the file no more valid PHP.

Hello,

On the last prettier version at this time and last php plugin version, those 2 code snippets make the php file invalid after.

SNIPPET 1

Before:

<?=$this->input('before') ?><?=$this->numeric('value');?><?=$this->input('after') ?>

After:

<?=
      $this->input('before')
      $this->numeric('value')
      $this->input('after')
?>

SNIPPET 2

Before:

<?php /* Some text */ 
if ($this->context ==='cars' || ($this->context !=='cars' && $this->editmode)) : ?>

After:

 /* Some text */<?php
/* Some text */
?>if (
    $this->context === 'cars' ||
    ($this->context !== 'cars' && $this->editmode)
): ?>

Hope it help to achieve a stable version.
Big thumbs up for this wonderfull plugin !

Reproduce the formatter output with the two PHP snippets shown in the issue using the current Prettier PHP plugin. Trace the formatting path responsible for combining or moving PHP tags, then add regression coverage confirming both formatted results remain valid PHP.
