Merge branch 'hotfix-2.2.26'
Events directly exported from MISP and imported to another instance failed on edit, fixes #259

- Events exported were enclosed in a <response> tag, which the sync automatically filters out, but a manual export and import would fail on edits

- added a conditional that removes the <response> tag if an event is encapsulated in a request to the edit method
