Describe the bug

While trying to use context.GetOrCreateSchemaAsync() I'm running into the following exception:

InvalidOperationException: The input schema must be an OpenApiSchema or OpenApiSchemaReference.
Microsoft.AspNetCore.OpenApi.OpenApiSchemaService.UnwrapOpenApiSchema(IOpenApiSchema sourceSchema)

This happens because it's trying to get the Target of a schema reference, but that returns null.
After some debugging I found that the target was null because OpenApiWorkspace._IOpenApiReferenceableRegistry had part of the schemas stored with keys with the base uri concatenated twice, for example: https://openapi.net/fa86ef4d-6f86-4937-9dee-98962f2eb26b#/components/schemas/https://openapi.net/fa86ef4d-6f86-4937-9dee-98962f2eb26b/components/schemas/SchemaX.

The issue appears to have been introduced with the following change: aa38ac3#diff-b3dad275078842738dacaa138dfd61e465a90ef85b68650304c791e0d487347cL26 , where RegisterComponent supported the full location while RegisterComponentForDocument only expects the component id.

Expected Behavior

Open API document is generated correctly without errors.

Steps To Reproduce

Unfortunately (or fortunately) I am having a hard time reproducing this in a minimal project, but I think looking at the code the issue is clear.

Exceptions (if any)

InvalidOperationException: The input schema must be an OpenApiSchema or OpenApiSchemaReference.
Microsoft.AspNetCore.OpenApi.OpenApiSchemaService.UnwrapOpenApiSchema(IOpenApiSchema sourceSchema)
