Add new option to link for new apps

[isaacroldan]

WHY are these changes introduced?

There is a bug for complex templates where some default config gets discarded.

Some context:

• When linking, if the remote and local clientId don't match, we were considering that as unable-to-reuse-current-config
• This makes sense in the context of running a command with --reset, you are linking to a different app, we need to create a new toml and import the config from the remote app, we can't reuse the existing config. But it's there in the previous toml in case you want to copy it over.
• This is not true for new apps, in that case this would be the first link, so if the config from the template is valid but missing the apiKey, we can just update that field, no need to discard the contents of the toml!

WHAT is this pull request doing?

• If the app is new (from app init) and has a current config format, we can ignore the api-key value and treat it as a valid config.

Could we get a test -- to prevent a future regression on this?
