Bug 34768: Remove checkbox column from relatives fines on OPAC

Bug 34768: Remove checkbox column from relatives fines on OPAC

When a patron has a guarantee and can see their fines on the opac and
an opac payment plugin is enabled there is an error on the 'Charges'
tab.

The table uses a 'COLSPAN' variable which is set to 5 or 6 depending on
if OPAC payments are enabled. The guarantees table has one less column
than the patron's however, so it is going out of range and causing a JS
error. Additionally, we are adding a column to the child's table which
is not used as their fines cannot be selected for payment at this time.

This patch removes the checkbox column and sets the colspan directly to
4

I also fix an issue where the table is not being set as we need to
reference the patron object in the guarantor info to obtain the id.

To test:
1 - Set system preference: AllowStaffToSetFinesVisibilityForGuarantor to
    allow
2 - Find a patron
3 - Add some fines to their account
4 - Install and enable an opac payment plugin
    (https://github.com/bywatersolutions/koha-plugin-pay-via-govolution
    for example)
5 - Sign in to OPAC as borrower
6 - Go to 'Charges' tab
7 - Select a fee
8 - Confirm 'Make payment' button enabled and 'amount to pay' is
    updated
9 - Add a guarantee to patron in staff interface
10 - Set 'Show charges to guarantors' to 'Yes'
11 - Add and pay a fine for the child
12 - View guarantor account on the OPAC
13 - Confirm you now see child's charges
14 - Confirm selecting your own fees does not enable the button or
     update amount to pay
15 - Note JS error in console
16 - Apply patch
17 - Reload patrons page
18 - Confirm the table loads correctly (no JS error)
19 - Confirm selecting a fine updates the total and enables button
20 - Disable the payment plugin
21 - Confirm the display is still correct, no errors
