OAuth2 realm config - updating 'scopes supported' requires a restart

[lscorcia]

Describe the bug
Hi, very small issue here. When editing the "scopes supported" field in the OAuth2 realm config, a server restart is required to make sure the scopes are updated in the metadata endpoint. It should be possible to update those at runtime.

To Reproduce
Steps to reproduce the behavior:

1. Go to Services > OAuth2 Provider
2. Click on Supported Scopes, add a new scope
3. Visit the metadata endpoint https://yourhost/openam/oauth2/realms/root/.well-known/openid-configuration
4. See the new scope is missing.
5. Restart the webapp
6. Visit the metadata endpoint, see that the new scope is now present.

Expected behavior
The new scope should be immediately visible.

Additional context
It seems that the issue was already fixed in the other fork openam-jp: https://github.com/openam-jp/openam/pull/155/files .
The fix should be applicable to this project too by applying the same change here:

OpenAM/openam-oauth2/src/main/java/org/forgerock/oauth2/core/RealmOAuth2ProviderSettings.java

Lines 1036 to 1038 in 4835723

	loginUrlTemplate = null;
