fix(gl-report): group by cost center only if include_dimensions is checked

[nextchamp-saqib]

if group_by_voucher_consolidated is checked the ledger entries are differentiated by voucher_type, voucher_no, account and cost_center

Cost Center is just another dimension, so it should be treated similarly. Hence ledger entries should be grouped by cost_center only if include_dimensions is checked.
