Remove implicit dependency on loading activesupport
Bump version to 1.1.2
Move on_end block before recording so it will always fire.
In the previous configuration, the on_end might not be added before the call actually ends if a user hangs up during the recording phase. Putting it here will better ensure it is added properly.
Merge branch 'hotfix/1.1.2' into develop
