[Desktop] GH not added to AC when "Allow contribution to videos" is unchecked

[LaurenWags]

Description

If you uncheck "Allow contributions to videos" in auto contribute settings, GitHub pages (ex. github.com/laurenwags) will not be added to your AC list even if it meets the length/time requirements.

Steps to Reproduce

1. Clean profile 1.10.x
2. Enable Rewards
3. Modify AC settings to uncheck "Allow contribution to videos"
4. Visit a GH page for a user for length/time required.

Actual result:

GH page is not added to AC list, if you open DB, it is not added in DB either

Expected result:

Since the GH page is not a video, it should be added to AC list
