Bug 13355: System preferences tab value wrong in templates

This patch fixes a bug on the system preferences tab templates.

To test:
To reproduce:
(1)
- Choose a tab on the sysprefs section (for example 'Enhanced Content')
- Right click on 'Enhanced Content preferences' title, and choose to 'inspect' the code
=> FAIL: you will see below the form tag something like:
<input type="hidden" name="op" value="save">
<input type="hidden" name="tab" value="">

(2)
- Do a syspref search (for example 'facet').
- Right click on one of the category titles (for example 'OPAC preferences')
=> FAIL: you will see below the form tag something like:
<input type="hidden" name="op" value="save">
<input type="hidden" name="tab" value="HASH(0x6e53050)">

- Apply the patch
- Repeat (1) and (2)
=> SUCCESS: you will see below the form tag something like:

<input type="hidden" name="tab" value="enhanced_content">
and
<input type="hidden" name="tab" value="opac">

respectively.
- Sign off :-D
