// These tests assume the following behavior from our mock logind server:
// * IsActive will return false
// * Lock() will emit an ActiveChanged(true) signal
//
// This should lead to the following behavior from our SessionManager plugin:
// * Starts active
// * Becomes inactive once it connects to logind and sees IsActive result
// * Becomes active once Lock() is called (which isn't really sensible, but
//   it's just a mock)
