Always set cast receivers during migration

Might prevent #11502 though I haven't been able to reproduce the issue

A dirtier but maybe more reliable workaround might be just set this as the default value, instead of setting it during migration. I think it is very likely that clients can overwrite this during configuration update and accidentally reset it to the default (empty).

This would prevent a user from completely removing reference to our cast receivers

Would adding an option to the web like "reset cast devices" which restore the default receivers list on the web be a good workaround then? Such accidents do occur and the user might be unaware of the actual reason, and only want to make it working again. Manually edit the xml file in this case is very undesirable.
