Fix bug that cannot add call if there are multiple calling account.

Repro steps:
1. setup multiple calling account (multi-sim or sip etc.)
2. make a ongoing call
3. click "Add call"
4. make another call in dialer

This is caused by recreating incall activity when adding new call that
will go through its lifecycle thus disconnecting the call with account
selection states automatically.
It's a regression caused by cl/162562378.
