Fixed IsLogFromCurrentProject to include all severities

[Mivekk]

Previously when executing following code LogCleaner would only delete overdue Error log files:

google::EnableLogCleaner(1min);

LOG(ERROR) << "Error hello";
LOG(INFO) << "Info hello";
LOG(WARNING) << "Warning hello";

And if we changed the order to for example:

LOG(INFO) << "Info hello";
LOG(ERROR) << "Error hello";
LOG(WARNING) << "Warning hello";

LogCleaner would only delete overdue Info log files and overdue Error and Warning files were ignored. To include all severities during LogCleaner's sweep I tested filepath for all severities in a IsLogFromCurrentProject function.

I'm not sure how I should modify cleaner test cases unfortunately

You can extend any of the cleanup_*_unittest.cc, for instance, here https://github.com/google/glog/blob/ac12a9e79440a2a89cc1c5617bb8f6db02035182/src/cleanup_immediately_unittest.cc#L62-L64 by additionally logging at the missing severities.

Please note that the unit tests need to be updated either way because these are failing now with your changes.

Updated unit test and all checks should pass now hopefully

[sergiud]

Unfortunately, the cleanup tests are still failing.

[Mivekk]

Fixed an issue different way

[sergiud]

The unit tests are still failing though.
