Fix Jetpack CP login

[hichamboushaba]

Description

This commit b28e928 that removed the Jetpack CP feature flag accidentally broke the Jetpack CP login, as it filtered out all of the JetpackCPConnected sites from the site picker's logic.
This PR fixes this.

This was identified after investigating this p1707195959834669/1705664280.448529-slack-C03L1NF1EA3

Testing instructions

1. Create a Jetpack CP site.
2. Confirm login works correctly to this site.

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.

This was a great find @hichamboushaba ! I really hope it helps reduce the number of users having trouble connecting to their stores.

PS: Tested it and login for jetpack CP sites works as expected
