Fixes messages.txt's modification timestamp not being updated.

This bug occurs on systems where writing a zero-length string to an
empty file does not update the file's modification timestamp.

This leads to the messages.txt being downloaded almost endlessly, causing
long delays for logged-in users. Visitors are not affected, because the
messages.txt is only updated for logged-in users.
