Show app name before it's processed by BSI

[mountaindude]

As of version 2.1.5 the log output for each app is:

...
2023-01-01T18:04:53.304Z info: About to process app a3e0f5d2-000a-464f-998d-33d333b175d7
2023-01-01T18:04:55.534Z info: Opened app a3e0f5d2-000a-464f-998d-33d333b175d7
2023-01-01T18:04:55.547Z info: Number of sheets in app: 5
...

Add a new log line, showing what the app name is.
This will make it easier to follow along what BSI is doing, what app is causing troubles etc.
