Add. Speed dial respects contacts user. (#2249)

* Add. Speed dial respects contacts user.

One user can not use speed dial numbers from contacts
associated with another user

* Make SQL query more efficient

* Add. Support find contacts by user groups as well

If contact has set any `user` or `group` then only this users can use speed dial numbers
in other case speed dial numbers are global for domain.
