Browser extension treats profile pages as repo pages

Created by: muratsu

Currently, the bext (browser extension) treats profile pages as repository pages and throws errors when parsing the URL.

Steps to reproduce:

1. Install and enable bext (browser extension)
2. Navigate to a profile page (example)

Expected behavior:

Bext (browser extension) should enable but not take any further actions

Actual behavior:

The bext (browser extension) tries to parse the github URL to figure out the repo & repo owner and throws an error.

Console error:

Uncaught Error: Could not parse repoName from GitHub url: https://github.com/muratsu
