As discussed with Chris Nighswonger on #koha, this patch
removes the calls to syslog and replaces them with warns
so that error messages generated by the labels code
are sent to the Apache error log. This avoids splitting
this sort of logging across multiple files and is consistent
with current practice in most of the rest of Koha.

This patch also moves the Labels tests into their own sub directory.
Due to a squash mistake this patch also includes the following:
Fixing up POD for C4::Labels modules
Also a minor bugfix and code refactoring.
