Unexpected comma at the end of condition block

Related to marko-js/language-server#170

The root cause may be this prettier package.
Also if I remove the problematic comma mentioned in the linked issue, prettier check will complain.

Expected Behavior

• It shouldn't cause Marko VSCode extension to insert the problematic comma
• prettier --check shouldn't expect the problematic comma to be there.

Actual Behavior

It wants to put a comma indicated here, which break the TypeScript checking for the props when passed to <person-card>

- <if(thisPerson.address && thisPerson.phone && thisPerson.age && thisPerson.nationality)>
+ <if(
+   thisPerson.address &&
+   thisPerson.phone &&
+   thisPerson.age &&
+   thisPerson.nationality, <!-- -----------------NOTICE THIS COMMA HERE! -->
+ )>
  <person-card
    address=thisPerson.address
    phone=thisPerson.phone
    age=thisPerson.age
  />
</if>

#39 now causes prettier-plugin-marko to not emit trailing commas for args by default (better aligns with prettier for js).
The core issue is in the language server which we'll track in marko-js/language-server#170
