What is the current behavior?

If you start the app through the launcher and the app is already open, we restart the logcat process and miss a few logs in the process. The current log line we're using to detect the start doesn't return the new PID at all and can conflict with apps with similar package names. This is a regression from #5755

What is the new behavior?

We accurately use a specific regex (/Start proc (?<pid>[0-9]+):(?<appId>.+?)\//) to find the exact appId and PID.
