[services] Backup - Send Log - Fix logic in terminate callback

Summary:
Depends on D4320

fixed the bug in if else in terminateCallback

The problem was that we were checking for the put reactor state only in the else if block, we should check for it always.

Test Plan: Services build, for now this went out of sync with the integration tests
