Fix issue when single line comment is ended by block comment suffix

[stirante]

While using the library I encountered an issue, where single line comment can be ended with */.
Example:

{
  // I commented a glob pattern like this "**/*"
  "test" : "Hello"
}

The error I got was invalid character '*' looking for beginning of value.

I added a simple check to not try and end the comment with */ if the comment is single line.

Looks great!

Thanks for the PR.

Will merge it soon.
