Accounts: Enable notification for accounts change (#2432)

* Enable notification for accounts change

* Fixed bugs in extHostAccountManagement.test.ts

* Fixed as commented:
1. Removed AccountWithProviderHandle
2. Use a private dictionary _accounts in ExtHostAccountManagement to cache all accounts and corresponding provider handles.
3. getSecurityToken gets provider handle from _accounts for specified account.
4. Added / changed unit tests for getAllAccounts & getSecurityToken
