Filters are not specific to one Tab

[rladstaetter]

Describe the bug
Filter settings (activation) should be specific to one log file, at the moment they arent.

To Reproduce

Steps to reproduce the behavior:

1. Open a log file
2. Change the default filter selection
3. open another log file

Current behavior

The second log file will get the settings of the first log file tab, which is not intended.

Expected behavior

Every log file/tab should have individual default settings, they aren't affect by settings for other log files.

Additional context

Side Note: If you restart and the logorrr.conf file gets persisted once, the behavior is correct.

Demonstrate the correct behavior with a test to get rid of such regressions in the future!
