Custom properties showing warning even when defined in context

[mraadgev]

When loading a custom property (to crate-o through an excel file), the properties are coming up with an error stating that they have not been defined in the context, even where the context has a reference for custom terms, and the term matches. See @rosanna-smith for an example

This occurs in the spreadsheet template for textType, available at https://www.ldaca.edu.au/resources/user-guides/crate-o/convert-spreadsheet/ and gives the warning "Property arcp://name,custom/terms#textType not defined in @context"
