fix[react-devtools]: initialize bridge only after domain is ready

[hoxyq]

Summary

Bridge and Store should only be created after the domain initialization. This is because Bridge is attempting to send some messages to the other end right after it has been created. They should not be created in model's constructor, because at this point there is no guarantee that the binding (which is used for messaging) has already been installed.

Tested manually.

Upstreaming plan

• This commit should be sent as a patch to the upstream devtools-frontend repo. I've reviewed the contribution guide.
• This commit is React Native-specific and cannot be upstreamed.
