Summary: Fixes T5144. This was incorrectly checking the //content// version, not the //head// version, so reverts would raise the "conflict" warning. Also fix a couple of FontAwesome icons. Test Plan: - Edited a document. - Reverted a document. - Opened two edit tabs. Edited one, tried to edit #2, got a warning. - Opened two revert tabs. Reverted in one, tried to revert in #2, got a warning.
