Syncing craft users to mailing lists doesn't work

[ghost]

Steps to reproduce

1. Allow public registrations and assign any registrations to a default group
2. Sync default group with Campaign
3. Register user via frontend (the user is activated)

Expected result: Registered user should appear in synced Campaign group, but does not.

Actual result: I did notice now that the user is synced as a contact in Campaign, but it's incomplete, because the user is not assigned to the mailing list Campaign is set to sync with.

I made a video of the whole thing here: https://drive.google.com/open?id=1REj3dMS9urR1mI2Hypl81XIABpy6-GVd

Edit:
Campaign 1.5.0
Campaign Pro 1.0.0

Thanks for reporting this! Fixed in v1.5.1.
