Form builder not merging custom and standard form sections with same name

[tomclement]

Description When a custom form section with the same name as a standard form section exists, attempting to add a standard form section (and its fields) with the same name as the pre-existing one fails - none of the fields in the standard form section is added

Expected Result When a custom form section with the same name as that of a standard form section already exists, attempting to add that standard form section should result in a merge of the form fields from both the custom and standard form fields

Resolved with rapidftr/RapidFTR/pull/697. Merge behaviour is now happening as follows:

• If a custom form section with the same name as one of the standard forms exists, that standard form section will already be checked in the Add Standard Forms pane.
• If the existing custom form section also has fields with the same names as fields in the standard forms, adding these fields will result in fields with duplicate names (this is expected behaviour since a form section can have multiple fields with the same (display) field name
