Fix conditional rendering of components

[routrohan]

Describe the bug Currently, all the blogs are rendered as cards even if users summarize blogs of their choice. There isn't a need to show the other blogs at that time.

To Reproduce Steps to reproduce the behavior:

1. Go to https://summit-mh.tech
2. Paste a valid Medium post URL and Click on Submit
3. Scroll down
4. You will find the other blogs being rendered there

Expected behavior The other blogs should disappear when the user summarizes a particular blog
