Update babel-plugin-htmlbars-inline-precompile to 3.0.1 to fix an issue with inline templates containing */.

Prior to this a template like:

hbs`some content */`

Would emit invalid JS:

Ember.HTMLBars.template(
  /*
    some content */
  */
  {
    // some stuff emitted by actual compilation
  }
)

The comment showing the original template was added as a developer aide (makes looking at files with many inline templates such as tests much easier), but without escaping */ we risk the template content itself breaking the JS parsing within the file.

This commit ensures that */ is escaped to *\/ which avoids the issue.

Fixes #391
