[Sim Bouncer] Show sim pin view.

Show sim pin view when sim is switched to a different locked sim.

Bug: 239799178
Test: Added a unit test and also tested by adding 2 esims and switching
between the two. I was able to reproduce the issue (the logs correspond
to the bug) and was able to see the expected behavior after making the
code change.
