Merge contacts - Unhandled Promise Rejection: Error: Not implemented

[fondraco]

Hi,

when you want to merge contacts, and click merge contacts button, the button starts spinning and keeps on spinning forever.

In the console there is this error

The contact that I'm trying to merge is with GitHub, the other(destination) is not.
