TestStorage.openOutputFile() subsequent writes to a file with "w" mode do not clear content properly

The testservices contentprovider does not handle write requests correctly.

echo "This is a line\n" > testfile adb shell content write --user 10 --uri content://androidx.test.services.storage.outputfiles/neatfile < testfile adb shell content write --user 10 --uri content://androidx.test.services.storage.outputfiles/neatfile < testfile adb shell content write --user 10 --uri content://androidx.test.services.storage.outputfiles/neatfile < testfile adb shell content read --user 10 --uri content://androidx.test.services.storage.outputfiles/neatfile

The output is This is a line This is a line This is a line

This is concerning because multiple writes to the same uri do not clear the old file contents.
