Add post to a collection

[AmTryingMyBest]

We had a collection test that performed these steps:

• Created a collection
• Added a post to a collection
• Verified this post was added to the collection
  Upon investigation, it seems the second two steps were not correctly executed.
  For this task, execute the above steps 2 & 3 as follows
• Add a post
• Add this post to a collection
• On the data view page, click the three dots
• Click on Add to Collection, the first option
• Select a collection, check the box against the collection
• Dismiss the collections modal
• Verify post is added to Collection
• Click on Collection
• Select Collection where post is added
• Navigate to Data View
• Verify post added to collection persists

NB: For this test, in the file collections.cy.js remove the .skip that skips the add post to collection test
