test fixes

[jmaasing]

This PR has test fixes for two things.

• The negativeFileTransferTest can fail in a very edgy-case where the test is run in docker and the file system is a separate docker volume. Apparently the file.setReadable(false) returns true even though the file is still readable. So just add a check too see if the file is still readable and if so skip the test. I also added some more information on the test asserts to make it more visible exactly what assert failed.

• TheApache log format test fails if the Locale is not US (or english speaking at least) since the abbreviated month names are used and those a localized. So the tests sets the local before checking the output of the log formatter. I also switch the 'expected' value with the 'actual' value to the correct positions in the assert statement.
