Bug: changing file extension causes file to be excluded from the project.

1. I had index.js, rename it to index.ts for Typescript.
2. Later changed the extension back to index.js

I did not exclude file from project inside webstorm, or exclude it inside .gitignore etc. But the file was not appearing when I tried cmd+shift+o

Tried:

• Restarting Webstorm
• Invalidating Cache and Restart

To fix this

• Deleted idea folder inside project
• Removed project from list of project in startup pane
• Loaded webstorm again using $> webstorm . from command line
