Bug 31325: Fix koha-preferences get
To reproduce:
$ perl koha/misc/admin/koha-preferences get MarcFlavour
This will output something like "HASH(0x55dd4d432840)".

To test:
Apply this patch and run the command again:
$ perl koha/misc/admin/koha-preferences get MarcFlavour
This should output something like "MARC21".

=head1 OPTIONS
COMMAND can be any of the following:
=over
=item B<dump> [ -o I<OUTFILE> ]
Dump all of Koha's system preferences as a simple YAML mapping into OUTFILE or
STDOUT.
=item B<load> [ -i I<INFILE> ] [ -f|--force ]
Reads system preferences specified in YAML in INFILE or STDIN. Will exit with a
status of 2, without setting any sysprefs, if any of the sysprefs do not exist.
Will also exit if any of the sysprefs are YesNo and have an invalid value.
If there is a Version syspref in the input, it will not be set in the database,
but it will be checked to make sure the running Koha version is equal or higher.
The script will exit with a status of 4 if this is not true. Pass the -f option
to skip this check.
=item B<get> I<PREFERENCE>
Print the value of the system preference PREFERENCE, followed by a newline. If
no such syspref exists, will exit with a status of 2.
=item B<set> I<PREFERENCE> I<VALUE>
Set the system preference PREFERENCE to the value VALUE. If no such syspref
exists, will exit with a status of 2. If the syspref already has that value,
will exit with a status of 3.
If the syspref is YesNo, will accept only a boolean value. The syntax is *not*
lax and must be 1 or 0.
=item B<clear> I<PREFERENCE>
Clears the value of the system preference PREFERENCE. If no such syspref exists,
will exit with a status of 2. Will set YesNo sysprefs to 'false'.
=item B<manual>
Print a longer, more detailed manual.
