Merges `release/4.4` into `develop`

This PR is largely a merge with two extra commits to fix a few things that the merge left in a broken state:

https://github.com/wordpress-mobile/WordPress-iOS/commit/9074d4b938e6fa86f3693fed9314b7819731d32a
This commit fixes an error with the `Podfile` where there was a mismatch in the stats pod between the main project and the today extension.

https://github.com/wordpress-mobile/WordPress-iOS/commit/354f29a2009235d8d6e2b63930856cd02ae36408
This commit just adjusts the Provisioning profiles as I had to update them in order for the project to build properly on the devices.
