fix(core): fix ESLint console warnings, Twitter redirect, and and scope usage (#1388)

* Use validator.js instead of regexp for validations in User Schema.

* Disables "Unexpected console statement  no-console" warnings

* Fixes redirection to wrong URL after login with social networks.

* Use ViewModel vm instead of $scope in manage social accounts controller.

* preserving the option to redirect to a specific URL as done in saveOAuthUserProfile() (thanks to @OneOfTheWorld for pointing out)
