fix(codecatalyst): activation fails in new dev environments #4811

Problem:
- The extension fails to activate in new dev environments:
`TypeError: Cannot read properties of undefined (reading 'scopeExpired')
	at pe.isScopeExpired`
- The issue also cascades to existing dev environment where things like activity heartbeat fails to activate because thisDevenv on codecatalyst/activation #L80 ends up being undefined

Solution:
- Provide a default for connection states if they aren't found. The reason this is neccessary is on L96 in codecatalyst/auth.ts we are making a call to this.isConnectionValid(), which then checks if the scopes are expired. This happens BEFORE the scopesExpired is available in the global state for 'codecatalyst.connections' causing the issue
