Reload repo after changing global release type

*Issue*
After changing the global release type setting the download versions list isn't updated.

*Usecase*
The user changes the global release type to see more module versions. After changing the settings the user goes to the modules download list and doesn't see any difference. He needs to manually refresh the modules list to see all versions. This is inconsistent to the behaviour of local release type changes.
This particular usecase was reported in the Xposed Installer experimental1 xda thread.

*Possible resolution*
Trigger a repro loader reload after global release type change.
