Used DEEP_STUBS for chained mocking

[nirikash]

Description

In case if code has chain of mocking objects, more compact is using of DEEP_STUBS mockito setting.
In this case objects can be mocked using fluent API style, like:

    @Mock(answer = Answers.RETURNS_DEEP_STUBS)
    private ISecurityService securityService;
...
        when(securityService.login()
                .from("REST")
                .authenticator(any())
                .with(any(IToken.class))).thenReturn(loginFinal);

Motivation

Compact and readable testing code
