Only show video call option in the call log when appropriate

This fixes two bugs we previously had:

1) If video calling was disabled in Settings, we would still show a video call option in the call log (fixed by checking the setting)

2) If a different app from Dialer inserted a video call into the history, we would incorrectly show a video call button in the call log (fixed by checking the account handle matches the default phone account)
