new create collection pop-up opens every time I click back after creating a new collection

Nature of issue?

• Found a bug

Details about the bug:

• Web browser and version: Google Chrome - 88.0.4324.182 (Official Build) (64-bit)

• Operating System: Linux Ubuntu 20.04.2.0 LTS (Focal Fossa)

• Steps to reproduce this bug:
  - First Go to collection
  - Click create collection
  - create a new collection
  - click back from the browser navigation bar without doing anything.

• Expected behavior: Simply get the user back to the collection window

• Current behavior: Every time it opens up another create collection pop-up which is normally an undesired behavior

I would like to work on this issue if it makes sense.

@catarak I have worked on this issue. I'll raise a PR if this issue is unintentional from the beginning. In my new branch after creating a new collection if a user clicks back button the browser will get the user back to the collection tab without poping up a new create collection overlay.

Thanks for opening this issue! I think this makes sense, though I don't agree with your suggestion about how to fix this. Instead, I think that when the user clicks on "Create Collection", the popup should appear but the URL should not change.

[Ajaya1000]

Yes, this makes more sense. Thanks for the suggestion.

@catarak I have raised a PR. Please review if this the way you suggested.
