Fix getDevSupportManager() in ReactDelegate

Summary:
In D54967130, this was moved to supply with the relevant DevSupportManager, however in Bridge mode in case of RELEASE(useDeveloperSupport = false), it would not provide BridgeDevSupportManager because of this check.

Changelog:
[ANDROID][FIXED] - Fixed `getDevSupportManager()` in ReactDelegate
