Fix an an undefined variable issue

[dkotter]

Description of the Change

In #574, we removed a try/catch block in order to fix an issue where distribution didn't fully work and the post ID value is 0, instead of undefined. But within that try/catch block, we were setting a $remote_id variable that is then used twice after that.

Because that code was removed, that variable then becomes undefined when it is referenced later, causing issues. Items will still distribute correctly but the connection will not be fully set up, so updates will not be pushed through.

This PR fixes this issue.

Alternate Designs

Benefits
