[ZF-8825] Lower-case lookup for "authorization" header

- A number of libraries, including CordovaJS, send the Authorization
  header as "authorization" (all lowercase); added a conditional check
  for this.
- Cannot test this, as it depends on the output of
  apache_request_headers().

[#3295] Fixed tests and logic flow

- Fixed the unit tests for the unsubscribe functionality. The table
  gateway was expecting the "delete" method now (not "update"), with
  only the "id" member in the array argument; additionally, we needed to
  test the return value, so I added a "will" clause.
- Altered the workflow of Callback to use a switch() statement for the
  "hub_mode"; this will make adding additional cases in the future
  easier, and allows us to raise an exception on an invalid mode.
