 As mentioned in #32127 and elsewhere, we should run the utf8 -> utf8mb4
 conversion on each db update.

 The main reason is that the server environment could change between
 updates.
 For example, if someone upgrades MySQL between 4.3 and 4.4's release, at
 present they'll update to 4.4 and still not have utf8mb4 support, even
 though WordPress will now be able to support it.
