Fixes ISSUE-44689: Format date using provided timezone in OBBindings#formatDate

Merged Cristian Berner requested to merge cristian.berner/openbravo:fix/44689 into release/20Q2

Previously as a side-effect date was being converted to UTC wrongly in OBBindings formatDate function. This fixes it by formatting using the local timezone as was previously done prior to the regression commit. Fixes display of date in some parameter windows that were relying on it (e.g. Costing Rules).

Fixes regression introduced in commit 4ec715bf
