Fix autolaunching.

We autolaunch in the following cases:
1. There is only a personal profile, and it has 1 launchable target
2. There are a personal and work profiles, they have 1 launchable
target each, which is the same app. If the app has declared support
for cross-profile interaction, we auto launch that app on the current
profile.

Test: manually tested combinations of test cases with 0/1/2 resolved
apps on personal, 0/1/2 resolved apps on work, with enabled/disabled
cross-profile intents for both directions (work-personal and
personal-work)
